For Managed WordPress
IONOS Managed WordPress installations offer a single sign-on option in addition to logging in with the username and password. With Single Sign-on activated, you can also use your IONOS account for the WordPress login.
The option to register through your IONOS account is automatically activated in your Managed WordPress installation. You can find this setting in your WordPress administration menu under Settings > IONOS > IONOS-OAuth. If the checkbox is checked, the link Login via IONOS is also displayed in your WordPress login screen.
If you are already logged in to your IONOS account, this link will open your WordPress administration menu. This opens the login page of your IONOS account. Log in there first, and then open the WordPress login screen again.
