Step 2. On the left side menu panel find “2FA FOR Confluence: U2F & TOTP” tab and click 2FA Configurations.


2FA configuration page


Below you will find a detailed description of 2FA configurations:


TOTP settings

Warning! It is not recommended to change these settings. Some Authenticator applications like Google Authenticator can handle default 30 seconds, so changing this value to a greater or fewer one won't allow users to log in.

1. Timestep is the interval in seconds between the previous and the new generation of the PIN code. By default, all Authenticators use 30 seconds. Change it only if you are using your own Authenticator with a different value.

2. Label will be displayed by the mobile Authenticator as an identifier for the underlying Atlassian application

3. Key size is the length of the generated secret key (needed for TOTP algorithm). By default, all Authenticators use 8. Change it only if you are using your own Authenticator with a different value.


Force settings

4. None - if you choose this option, 2FA will not be compulsory for Confluence users. If you need to make it compulsory - use others below.

5. All - it’s compulsory for all users.

6. Groups - it’s compulsory only for selected groups of users.

7. All except groups - it’s compulsory for all users except selected groups of users.
