The OATHAuth extension is a time-based one-time password (TOTP) implementation. It provides two-factor authentication via something you have (your phone or desktop client) and something you know (your user name/password). Client support is available for most feature phones, smartphones and desktops (see Client implementations).
The help page on Two-factor authentication provides information for end users on how to use this extension. However the special page used will also guide users.

OATHAuth also adds a key to the $wgRateLimits array to define rate limits for authentication attempts:
'badoath' => [ '&can-bypass' => false, 'user' => [ 10, 60 ], 'user-global' => [ 10, 60 ], ]
Note that the
user-global key is available only since 1.35.

- Granting access to enable OATHAuth
$wgGroupPermissions['user']['oathauth-enable'] = true;
The above will grant all registered users access to enable OATHAuth.
- Resetting a user token
In the event that a user both loses their token generator AND the recovery tokens; two-factor authentication may be removed from the user by deleting their row from the
oathauth_users database table.
Alternatively, a sysadmin with shell access may type on a command line
cd /path/to/mediawiki/extensions/OATHAuth/maintenance/ and then execute
php disableOATHAuthForUser.php "username" where
"username" is the user to have 2FA disabled.
