To enable two-factor authentication, administrators must allow users to use it, and then users enable it by themselves.

The steps to use two-factor authentication are as follows.

1. Click the gear-shaped menu button in the header.

2. Click Users & System Administration.

3. Click Login.
   

4. In the "Two-factor authentication" section, select "Allow users to use two-factor authentication".
   By default, the "Allow users to use two-factor authentication" option is selected.
   If you do not want to change the setting, skip step 4.

5. Click Save.
