=== Clock drift ===

If your 2FA device's [[Clock drift|clock becomes too inaccurate]], it will generate the wrong verification codes and you will not be able to log in. To prevent this, the 2FA device's clock should be kept reasonably accurate. Most smartphones and computers keep the clock in sync when they are connected to the Internet, and you will most likely not have to do anything as long as your device is online.

=== Users who are not in certain user groups ===

Currently users who are not Administrators <ref>Additionally, [[Wikipedia:Bureaucrats|bureaucrats]], [[Wikipedia:CheckUser|checkusers]], [[Wikipedia:Interface administrators|interface administrators]], and [[Wikipedia:Oversight|oversighters]] have access, but these groups normally only include administrators.</ref>

Edit filter managers, Page movers, and/or Template editors will have to submit a request at [[:m:Steward requests/Global permissions#Requests for 2 Factor Auth tester permissions]] to obtain access to 2FA (see [[m:Steward requests/Global permissions/2022-12#Requests_for_2_Factor_Auth_tester_permissions|request examples]]) this means most users will have to submit a request there.

== WebAuthn ==

[[File:Two-factor authentication on Wikimedia as of 2025 with WebAuthn screenshot.webp|thumb|Configuring WebAuthn as two-factor authentication]]

[[mw:Extension:WebAuthn|WebAuthn]] is another two-factor mechanism that may be enabled; it is currently not recommended as there is [[phab:T244348|no recovery mechanism]] for lost keys and it has less support from community volunteers. If you use WebAuthn and have a technical issue, you may lose access to your account forever.

WebAuthn may require you to logon on the same project that you have set it up on, when logging on in the future. For example, if you enroll WebAuthn here on the English Wikipedia, then log out, you will not be able to log on at the Spanish Wikipedia - you would need to log on here first. This is a [[phab:T244088|known issue]].

WebAuthn is not currently supported on the mobile apps (see [[phab:T230043|T230043]]).
