Signing in and two-factor

Protect your account with an authenticator app, a text code or a passkey.

Staff and merchants turn on two-factor from Profile. After your password, you enter a code from an authenticator app or a text message, or use a passkey.

A new device

A browser you have confirmed with a second factor is remembered for a while; a new one asks again.

Write to support from the contact page. We never ask for your password or a code.
