Google Authenticator app on Android
Can I use Google Authenticator for WordPress with the Android/iPhone apps for WordPress?
Yes, you can enable the App password feature to make that possible, but notice that the XMLRPC interface isn’t protected by two-factor authentication, only a long password.
I want to update the secret, should I just scan the new QR code after creating a new secret?
No, you’ll have to delete the existing account from the Google Authenticator app on your smartphone before you scan the new QR code, that is unless you change the description as well.
I am unable to log in using this plugin, what’s wrong ?
The Google Authenticator verification codes are time based, so it’s crucial that the clock in your phone is accurate and in sync with the clock on the server where your WordPress installation is hosted.
If you have an Android phone, you can use an app like ClockSync to set your clock in case your Cell provider doesn’t provide accurate time information
Another option is to enable “relaxed mode” in the settings for the plugin, this will enable more valid codes by allowing up to a 4 min. timedrift in each direction.
I have several users on my WordPress installation, is that a supported configuration ?
Yes, each user has his own Google Authenticator settings.
During installation I forgot the thing about making sure my webhost is capable of providing accurate time information, I’m now unable to login, please help.
If you have SSH or FTP access to your webhosting account, you can manually delete the plugin from your WordPress installation,
just delete the wp-content/plugins/google-authenticator directory, and you’ll be able to login using username/password again.
I don’t own a Smartphone, isn’t there another way to generate these secret codes ?
Yes, there is a webbased version here : https://gauth.apps.gbraad.nl/
Github project here : https://github.com/gbraad/gauth
Can I create backupcodes ?
No, but if you’re using an Android smartphone you can replace the Google Authenticator app with Authenticator Plus.
It’s a really nice app that can import your existing settings, sync between devices and backup/restore using your sd-card.
It’s not a free app, but it’s well worth the money.
Any known incompatabilities ?
Yes, the Man-in-the-middle attack/replay detection code isn’t compatible with the test/setup mode in the “Stop spammer registration plugin”,
please remember to remove the “Check credentials on all login attempts” checkmark before installing my plugin.
