Download an authenticator app + +Any authenticator app should work with Friendica. +Notheless, we recommend: + + - For iOS, [Matt Rubin's MIT-licensed Authenticator app](https://mattrubin.me/authenticator). + - For Android, [andOTP](https://github.com/andOTP/andOTP). + +### 2. Record your one-use recovery codes + +From your [two-factor authentication user settings](/settings/2fa), enter your password and click on "Enable two-factor authentication". + +You will be presented with a list of one-use recovery codes. +Please save those in the same place you are saving your Friendica password (ideally, in a password manager like [KeePass](https://keepass.info)). + +When you're done, click on "Next". + +### 3. Setup your authenticator app + +You have three methods to setup your authenticator app: + +1. Scan the QR Code with your device camera. + This will automatically configure your account on the app. +2. Click/tap on the provided **totp://** URl. + Ideally your authenticator app should be called with this URL and set up your account. +3. Enter your account settings manually. + Friendica is using default settings for token type, code digit count and hashing algorithm but you may be required to enter them in your app. + +**Tip**: If you have multiple devices, configure them all at this point. + +Then verify your app is correctly configured by submitting a code provided by your app. +This will conclude two-factor authentication configuration. + +**Note:** If you leave this screen at any point without having submitted a verification code, two-factor authentication won't be enabled on your account. +To complete the configuration, just come back to your [two-factor authentication user settings](/settings/2fa) and click on "Finish configuration" after entering your current password. + +## Disabling two-factor authentication + +You can disable two-factor authentication at any time by going to your [two-factor authentication user settings](/settings/2fa) and click on "Disable two-factor authentication" after entering your current password. + +You should remove your Friendica account from your authenticator app as it won't work again even if you reenable two-factor authentication. +In this case you will have to configure your authenticator app again using the process above. + +## Managing your one-time recovery codes + +When two-factor authentication is enabled, you can show your recovery codes, including the ones you've already used. + +You can freely regenerate a new set of fresh recovery codes, just be sure to replace the previous ones where you saved them as they won't be active anymore. diff --git a/mod/settings.php b/mod/settings.php index 536c833542..45f11cdb6c 100644 --- a/mod/settings.php +++ b/mod/settings.php @@ -67,6 +67,13 @@ function settings_init(App $a) ], ]; + $tabs[] = [ + 'label' => L10n::t('Two-factor authentication'), + 'url' => 'settings/2fa', + 'selected' => (($a->argc > 1) && ($a->argv[1] === '2fa') ?
