I am a user, how can I enable or disable two-factor authentication?

Several scenarios:

If the administrator of your account enforces two-factor authentication for all accounts:

No action is required on your part; two-factor authentication is enabled by default and cannot be disabled.

If the administrator does not enforce two-factor authentication:

You may of course decide to activate it only for your account, and later deactivate it as you wish.

Here is the procedure to follow:

1. Once logged into your user account, go to your profile settings.

2. The profile section is displayed by default.

3. A selector is available: if it is greyed out, two-factor authentication is disabled; if it is blue, two-factor authentication is enabled.

4. Click this switch until you obtain the desired colour.

Good to know: if your account administrator decides to activate and then deactivate the feature, it is your responsibility to activate it manually for your user account according to the steps described above.
