First-Time Revolut Login: A Beginner’s Guide to Setting Up Biometric Authentication

Your first time opening the Revolut app brings both convenience and a security decision. The application greets you with a phone number field, asks for an SMS verification code, and then requires a passcode—but before settling into that routine, you should understand how to replace the passcode with Face ID or fingerprint authentication. Most new users complete the initial Revolut login without exploring these options, then discover weeks later that biometric authentication exists. Setting it up immediately takes minutes and avoids the habit of typing a numeric code every time you need to send money, check balances, or approve a transaction.

The Revolut app has been downloaded more than 70 million times since 2015, making it one of the world’s largest fintech platforms. New users are often drawn to its multi-currency wallets, investment features, or physical card options rather than its security architecture. Yet the first login experience shapes every subsequent session. Understanding how phone-based authentication works, why you receive an SMS code, and how biometric login differs from a passcode sets the foundation for secure and frictionless access to your account. This guide walks you through that initial setup and explains the practical differences between authentication methods.

What happens during your first Revolut login

The first screen after launching the Revolut app asks for your phone number. This is not a username or email; Revolut uses your phone as the primary identifier. Type the number in the format displayed (usually with country code included) and tap the verification button. Within seconds, you should receive an SMS message containing a six-digit code. This code is time-limited and valid for approximately 10 minutes; if you wait longer, you may need to request a new one.

Type that SMS code into the app and proceed. At this point, Revolut begins the process of device binding—linking your phone or tablet to your account. This is a security measure designed to prevent unauthorized access from other devices. During this first Revolut login, you are establishing that this particular device is trusted. The system records details such as the device model, operating system version, and a unique identifier that persists even if you restart the phone.

After code verification, you will be asked to create a numeric passcode, typically four to six digits. This passcode is distinct from your PIN if you have a physical Revolut card (which is for ATM withdrawals and in-person transactions). The app passcode is what you enter each time you log in after the first session. Most users at this stage simply create a code and move forward, unaware that this passcode is optional and can be replaced almost immediately with a more convenient biometric option. Taking an extra two minutes to set up Face ID or fingerprint authentication during your first login means you will never need to type that code again.

Why SMS codes matter for your first login

The SMS verification code is a form of multi-factor authentication. Even if someone obtains your phone number, they cannot complete a Revolut login on a new device without receiving that SMS message on your phone. This assumes your phone number has not been ported to a different SIM card through social engineering or a carrier mistake—scenarios that are rare but possible. For the vast majority of users, SMS codes provide a meaningful barrier against account takeover.

SMS, however, is considered a weaker form of second factor because it can be intercepted or redirected in certain circumstances. Revolut therefore layers additional protections on top. Once you complete your first Revolut login and subsequent sessions, the app uses device binding to recognize your phone. If a new device attempts to log in, the system may trigger additional verification steps, email notifications, or require approval from an existing trusted device. The SMS code is the entry point; device binding is what prevents casual reuse of that phone number elsewhere.

For this reason, protecting your phone number is almost as important as protecting your password. If you port your number to a new carrier, inform Revolut through the app settings beforehand if possible. If you receive unexpected SMS codes from Revolut when you have not attempted to log in, that is a sign that someone may have your number and is trying to access your account. Contact Revolut support immediately in that scenario; your device binding and passcode/biometric authentication should prevent access, but the attempt itself warrants investigation.

Setting up biometric authentication instead of typing a passcode

After your first Revolut login and passcode creation, open the app settings—usually found in the profile icon or menu at the bottom or top of the screen. Look for “Security,” “Login methods,” or “Authentication” options. Within that section, you should see an option to enable “Biometric login,” “Face ID,” or “Fingerprint authentication,” depending on your device type and the version of the Revolut app you have installed.

On iOS, selecting Face ID will ask you to confirm your face using the device’s TrueDepth camera. On Android, the process for fingerprint varies slightly depending on your phone manufacturer, but the app will guide you through capturing your fingerprint data. The biometric information is stored locally on your device and never sent to Revolut’s servers. This is a crucial distinction: your face or fingerprint is not stored in Revolut’s cloud. Instead, the device itself verifies you locally and sends a confirmation to the app that authentication was successful.

Once biometric authentication is enabled, your future Revolut login flow becomes: open the app, see the biometric prompt (either “Look at phone” for Face ID or “Touch fingerprint sensor” for Android), and access your account. No passcode typing required. The entire process takes one to two seconds. If you have multiple fingerprints enrolled on your phone or multiple people configured on a shared device, be aware that any of them can unlock the Revolut app through their own biometric. This is a convenience trade-off you should evaluate based on your household situation.

If you later disable biometric authentication—perhaps because you upgrade your phone or want to return to a passcode—you can toggle it back on at any time through the same security settings. The reversal is immediate and does not require you to contact support or undergo a new verification process.

Device binding and why it affects your login experience

When you complete your first Revolut login, the app silently activates device binding. This means the account is now registered as trusted on that particular phone. If you later attempt to log in on a different device—a new phone, a tablet, or even a friends’s phone—Revolut will recognize it as a new device and may require additional verification steps. You might receive a notification on your original trusted device asking you to approve the new login, or you might be sent an additional SMS code or email confirmation link.

This is intentional security design. It prevents someone who has your phone number and intercepts an SMS code from immediately accessing your account on a brand-new device. Device binding makes the SMS code less portable and therefore less valuable as a sole attack vector. However, it also means that if you lose your phone, you cannot instantly regain access to Revolut from a new phone without a recovery process.

For account recovery after losing your device, Revolut allows you to verify your identity through alternative methods: email verification, security questions, or support contact. The company recommends that you keep your registered email address up to date and consider creating a backup recovery method before you lose access. Some users store a photograph of their recovery information or security questions in a password manager or secure cloud service, but never store your actual passcode or biometric backup this way.

Why biometric login is more secure than a numeric passcode

A four-digit passcode can theoretically be guessed in up to 10,000 attempts. A six-digit passcode raises that to 1 million combinations. In practice, Revolut prevents brute force by limiting login attempts and implementing account lockouts after a certain number of failures, so the numeric threat is lower than theory suggests. However, biometric authentication solves a different problem entirely: it cannot be guessed or brute forced because it is not a number that exists in a predictable sequence.

Biometric data can be spoofed—a high-quality photograph might fool some Face ID implementations, or a lifted fingerprint might theoretically activate some sensors—but modern devices have improved considerably. Apple’s Face ID includes checks for liveness (detecting whether it is a real face rather than a photo), while most Android fingerprint sensors use multiple sensors and advanced matching algorithms. The attack surface is narrower than you might think because an attacker would need physical access to your phone, your face, and your fingerprints simultaneously.

The real advantage of biometric login is that it combines strong authentication with convenience. A passcode typed every time creates friction, and friction encourages shortcuts: choosing simple numbers, writing it down, or sharing it with family members. Biometric authentication removes that incentive. It feels as secure as it actually is, which is rare in security design. For this reason, if your device supports Face ID or fingerprint, enabling it during or immediately after your first Revolut login is one of the highest-value security decisions you can make.

Practical steps for your first session

Start by downloading the Revolut app from the Apple App Store or Google Play Store. Open it and enter your phone number. You should receive an SMS code within 30 seconds. If you do not, check that your phone plan has SMS enabled and that you entered the number correctly. Wait a full minute before requesting a new code; carriers sometimes delay messages briefly.

After entering the SMS code, you will be asked to create a passcode. Before you move on, take a second look at your device: does it have Face ID, TouchID, or a fingerprint sensor? If yes, use a memorable six-digit passcode rather than something too simple, because you will only need to type it once more. After completing the initial setup, go directly to Settings, find Security or Authentication, and enable biometric login. Test it by logging out and back in to confirm that Face ID or fingerprint works as expected. If you have any trouble, you can always revert to the passcode method.

During account creation, you will also need to upload an identity document (passport or ID card) and take a selfie for verification. This is KYC (Know Your Customer) compliance; Revolut is a regulated financial institution in the UK, EU, US, India, and Mexico, and identity verification is a legal requirement. Complete this before attempting to fund your account or use your Revolut card, because unverified accounts have withdrawal and spending limits. For a detailed walkthrough of the entire process, including example screenshots and troubleshooting, you can refer to revolut login resources provided by the company.

What to do if you forget your passcode or lose access

If you successfully set up biometric authentication, forgetting your passcode is not a practical problem because you will not be typing it regularly. However, if you have not enabled biometric login and you have forgotten your passcode, you can use the “Forgot passcode?” link on the login screen. Revolut will verify your identity through your registered email address, a recovery code, or your phone number and SMS code. The process typically takes a few minutes.

If you lose your phone entirely, the recovery process is more involved. You will need to download the Revolut app on a new device, enter your phone number, receive an SMS code, and then provide additional identity verification to regain access. Revolut may ask you security questions, require a video call, or request documentation to confirm you are the legitimate account owner. This is why device binding exists—it makes unauthorized access harder, which also makes account recovery harder if you are the legitimate owner but do not have access to your original phone.

To minimize recovery difficulty, keep your registered email address current, consider saving a recovery code (if Revolut offers one during setup) in a secure password manager, and ensure your phone number has not changed without your knowledge. If you upgrade your phone or switch carriers, log into Revolut from the new device while you still have access to the old device, so that the new device can be added to your trusted device list. These precautions take minutes during setup but can save hours of frustration if something goes wrong.
