BioID Facial Recognition App
The BioID facial recognition app for Android platform allows you to try out BioID's strong and convenient face recognition, which you can easily integrate into your own applications, and lets you log in to linked applications simply by taking a selfie.
Getting started is simple. Once you've installed the app (Android 5 and above):
- Enter credentials from your existing BioID account or register for a new account
- Enroll your face with a few quick selfies
- Enjoy simple, secure login!
Register your device
When you first open the Android app you will be prompted to link your device to a BioID account.
Please enter the username and password of your BioID account!
Enroll your face
If the BioID account you registered does not already have an associated face template, you will be asked to enroll your face by taking a few selfies.
Press Yes to start the enrollment. You will be guided through the enrollment process. Hold your phone at eye-level then press Continue.
You'll be prompted to move your head ... please move your head slightly.
More images are needed. You'll be asked to turn your body 90 and phone degrees. After turning, press Continue to start image capture.
Change your position
Turn a quarter turn so you have different lighting conditions and background. This provides varied lighting and helps make sure that you can be recognized quickly in the future, no matter where you are.
How many turns?
You will change your position a total of 3 times. Each capture process takes one pair of photos.
During enrollment the following information will be displayed
The enrollment process starts and uses your uploaded images.
Enroll more images at any time
From the start screen press in the menu Enroll face.
You may be asked to enter your BioID account password. This is to ensure that only you are enrolled.
Verify your face
Once you have enrolled, you can test face recognition.
Start by holding your phone at eye-level, then press Verify from the start screen.
While images are captured you will see the following
This message means we are searching for your face. Is it completely visible on the screen?
Once we find your face, the first photo is automatically taken.
The first photo is captured, move your head sightly as instructed. If you have enabled challenge-response in your BioID account, you'll be asked to "Follow me". In this case you must turn your head in the directions indicated. This protects against video replay attacks.
The Android app is looking for small, natural movements, but keep your eyes on the screen. It will automatically take a second photo.
If the sample head does not move, it means no motion was detected. Move your head again in the indicated direction.
The photos have been captured and are being uploaded.
During verification the following information will be displayed
The verification process starts and uses your uploaded images.

- No motion detected.

Be Recognized Faster
Are you sometimes not recognized on the first try?
Any time you need to be recognized, BioID captures one or more photos of your face and compares your unique features with those extracted from your enrollment photos. Keep the following tips in mind for best results.
Always hold your phone at eye-level
If you wear glasses, try to avoid reflection. Usually this can be corrected with a slight movement.
Stick to frontal views and nearly frontal views of the face
When asked to move your head, keep the movement small and keep your eyes on the screen. Only a slight turn of the head is required.
Enroll more images with different lighting conditions
Lighting conditions can affect recognition, if it is different from the lighting when you enrolled. This is not just a matter of intensity (dark vs. very bright light). Because of the shadows that are (or are not) cast, great differences are caused by the direction of the light (frontal lighting, backlight, from above, from the side).
The best way to prevent lighting-related problems is to enroll more photos in the different conditions you might experience during recognition. If you have persistent trouble being recognized, try to vary the light. This can be done by turning your head and phone slightly, getting up and turning your whole body, moving to a different part of the room, adjusting the angle of a lamp, or turning lights on or off. Don’t forget that your monitor and phone are also light sources!
Understanding error messages
When you are not recognized, you may see one of the following error messages.
|Failed Enrollment / Failed Verification||Lighting very different from that at enrollment.||Try to vary the lighting direction or intensity. This might only require a slight movement (see above for tips).|
|Reflection on glasses.||Turn slightly to avoid glare. Move away from close, bright lights (e.g. your monitor).|
|Head turned too far.||Hold phone at eye level and look straight. When asked to move, do so only slightly and keep your eyes on the screen.|
|Your face has changed significantly since you were last recognized (very rare - e.g. serious accident or major surgery).||Enroll more pictures, either through your app or on the BioID Playground. If you also have trouble being recognized on the Playground with your webcam, you may log in with your password (Depending on your authentication settings you may also need to enter a security code sent to your phone or email).|
|Failed liveness detection or challenge-response failed||Head turned too far.||Look straight with phone at eye level. When instructed move only slightly and keep looking at the display.|
|You moved the phone.||Turn your head slightly while holding the phone steady.|
|Head movement was 'flat'.||Turn your head, don't just tilt or move in a straight line.|
|Photo or video detected.||Recognition requires a live face, not a photo or video.|
|Head turned wrong direction - only if challenge-response is enabled!||Turn head only slightly in the direction indicated by the sample.|
|No motion detected.||You didn't move your head.||Turn your head slightly as indicated.|
|No face found.||Face / eyes covered with hair, clothing, dark sunglasses, etc.||Your whole face and eyes must be visible.|
|Lighting much too dark or bright.||For better lighting move a little, turn a different direction, or adjust your light.|
|Head turned much too far.||Hold phone at eye level and look straight. When asked to move, turn only slightly and keep your eyes on the screen.|
|Face cut off.||Hold the phone far enough, so that your whole face is visible.|
Manage your BioID Account
The BioID app is tied to your BioID account.
Manage your biometric template
You can view and manage the images used for your enrollment from your profile page.
This includes any biometrics enrolled through the BioID app or through the BioID Playground website.
You can delete single images or all images.
If you delete all images your face template will also be deleted and you will not be able to log in with your face unless you enroll more photos.
Manage your authentication settings
You can also manage multi-factor authentication, which protects you by requiring any two of the following factors when you log in (password, biometrics or security code sent via email, SMS text message or TOTP authenticator app).
Access your BioID account from a mobile browser by using the BioID facial recognition app
If you access this website through your mobile browser and have the BioID app installed, you can log in with biometrics by pressing Log in, then at the bottom of the screen press the button BioID Mobile. This will open the app; you'll be verified and then returned to the browser session and logged into your account.
You may also enroll or test verification (both face and voice) through the BioID Playground. Enrollment and verification on the Playground website requires a browser that supports either HTML5 media capture or the Microsoft Silverlight plug-in (which are not supported by most current mobile browsers).
