A free program for Android, by Salesforce.com inc..

Salesforce Authenticator is a free mobile app that provides two-factor authentication for your Salesforce accounts. It works on all mobile devices running Android 8.0 or above. It also supports a variety of other services that utilize time-based one-time passwords (TOTP).

The app automatically generates a one-time verification code that you can use to confirm transactions or log in to websites. You can also use the code when you’re offline.

How do I get started?

If you already have a Salesforce account, you can use the app to add two-factor authentication. Just install the app and follow the on-screen instructions to set up your account. If you don’t have a Salesforce account, you can create one.
