Today, we're rolling out password-based login for all users.
If you still have an active login session, you can create a password on the Settings page.
If you previously signed up for an account at ChatUML with the magic link, you can still log in by ticking the "I don't have a password" box on the login page.
Since the magic link login feature will be deprecated soon, setting your password as soon as possible is recommended to avoid losing access to your account.
For newly signed-up users, you will be using password by default.
