Sinch ID Authentication using a Security Key

A security key uses a hardware device (like a YubiKey) or your platform's built-in authenticator (like Touch ID or Windows Hello) to verify your identity. Security keys follow the FIDO2/WebAuthn standard.

To set up a security key, take the following steps:

1. Sign in to Sinch ID and go to Sign-in & Security:
   
   

   In the Authentication Methods (MFA) section, under Security key, click Setup.
    

2. An intro screen explains what security keys are:
   
   
   
   Click Use security key to continue.
    
3. Your browser shows a WebAuthn dialog. Follow the prompts to insert and tap your hardware key, or use your platform authenticator (Touch ID, Windows Hello, etc.).
    

4. Give your security key a name so you can identify it later:
   
   

   Click Continue.
    

5.  A confirmation message is displayed informing you that the security key was registered.

    

6. If this is your first MFA method, Sinch ID shows a recovery code. Copy or write it down and store it somewhere safe.
   
   Note: The recovery code only appears when you enrol your first MFA method. If you already have another method enabled, this step is skipped.

A confirmation message is displayed informing you that the setup is complete. You can safely close this tab.
