Extension:OATHAuth

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).

Usage
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.

User permission

 * Granting access to enable OATHAuth

Users should be given access to the   user right so that they can enable it at Special:OATHAuth (a link to which appears at Special:Preferences).

The above will grant all registered users access to enable OATHAuth.

Administration

 * 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   database table.

A sysadmin with shell access may type on a command line   and then execute   where  is the user to have 2FA disabled to have it disabled.
