How Do I Set Or Reset My Password?
Change your password on the Profile page under Account Details - it asks for your current password first. Forgot it, or signed up with Google and never had one? Use Forgot Password on the login page: enter your email, follow the emailed link and set a new password.
Updated
There are two paths, depending on whether you can sign in.
If You Are Signed In
On your Profile page, under Account Details, find the Password card. Enter your current password, then the new one twice, and press Update Password.
If You Cannot Sign In
Use the Forgot Password link on the login page. Enter your account email and press Send Reset Link. Follow the link in the email to the Set New Password page, choose a new password, and you are signed back in. If the link has expired or was already used, request a new one the same way.
Signed Up With Google And Have No Password?
An account created with Google has no password, and the change form on Profile requires a current one. To set your first password, use Forgot Password instead - the reset flow does not ask for a current password. Afterwards you can sign in with either Google or your password.
Password Requirements
Use at least 8 characters, with an uppercase letter, a number and a special character.
Resetting your password does not change anything else on your account - your websites, domains and settings are untouched.
