Anchor supports one-time password (OTP) as its email MFA method. Each identity is assigned a dedicated mailbox — simply configure a forwarding rule with your email provider to route OTP codes to Anchor during identity creation, reauthentication, and agent sessions.

Step 1: Add Email MFA as an authentication method

  1. Go to the Identities page and select your identity.
  2. Choose Preset authentication — the available authentication flows will appear below.
  3. Click the Add flow button to create a new authentication flow.
  4. Enter a name for the flow and click Add.
  5. Select the Email MFA checkbox under Authentication Methods. Include any other authentication methods needed for this login flow.
  6. Click Save Changes in the top-right corner.

Step 2: Create an identity that uses the Email MFA authentication method

After creating the Email MFA authentication method:
  1. Create a new identity.
  2. In the credentials window, choose the Email MFA authentication method.
  3. You will receive a dedicated mailbox (for example, zesty-vale7820@mfa.anchorbrowser.io).
  4. Set up a forwarding rule from your mailbox to your dedicated mailbox.
  5. Optionally, test the forwarding flow using the detailed instructions.
