BioLogin

BioLogin lets you verify your identity by taking a selfie instead of entering a password. There are two entry points: the main selfie capture screen and a legacy alternate entry screen.

BioLogin intro card

The BioLogin link the business sends you includes the following built-in settings:

  • A session token (pid) — required, identifies your session
  • A server address (server_url) — required, tells the app which region to connect to
  • An optional access token (tk or token) and language override (ln or language)

Screens​

  • Main selfie screen (current BioLogin experience)
  • Legacy alternate selfie entry screen

How BioLogin Works​

Main Selfie Screen​

  • Purpose: Walk you through an introduction, selfie capture, preview, and result in one place.
  • When you arrive here: You open a BioLogin link sent by the business.
  • What you do: Tap Start, take a selfie, review the image, and receive your result. You can retry if the result is unsuccessful.
  • What happens next:
    • Success — you are taken to the Completion screen, which then returns you to the business website.
    • Failure — you stay on the BioLogin screen and can try again.

How Your Session Is Kept Safe​

  • Sensitive link settings are saved locally in the browser after you open the link.
  • The original link settings are removed from the address bar after saving.
  • A time limit is applied so saved data does not persist indefinitely.

Screens You Move Through​

  • Intro — instructions and a Start button
  • Capture — live camera view for your selfie
  • Preview — you confirm or retake the selfie
  • Result — shows whether verification passed or failed

What Gets Sent for Verification​

When you submit your selfie, the app sends your session token, the selfie image, information about your device, and (if enabled) your location sharing data.

Language​

  • The language shown matches the preference set in your link or the business's default.
  • Arabic content automatically switches the layout to right-to-left.
note

On a successful result, BioLogin takes you to the Completion screen, which then redirects you back to the business.
