You can now use your Google account to login to Moodle. On the Login page, simply click the Google icon, and login normally.
If you already have a Moodle account using the same email address, Moodle will send an email to your account to link the two accounts together.
You don't have to use your Google account, so if you're happy logging in the way you are now, you can continue to do so.
Thanks!
