How does the Authenticator App work?

The Authenticator App generates push notifications with codes you can scan and enter. Using this service, you can enable extra security to your online accounts on websites that use time-based one-time passwords (TOTP). This service is maintained by Multi Factor Authentication, an authentication service that provides secure, easy, and convenient access to online accounts.

How does it keep your accounts safe?

The codes are one-time tokens that you can use to protect your online accounts on websites that support TOTP. With Authenticator App, you can use your smartphone to generate these codes and to scan them. This way, you can use the service without having to remember or enter a password.
