To log in to quay.io via the `docker login` command, you will need a username and password.
The username required is the username for your Quay.io account. This is not the email address you may use to log in, but can be found beside your gravitar in the upper-right corner of Quay.io once you are logged in.
If you log in through a single sign on service (such as Google Oauth) you will need to visit your Account Settings page and create a password before using the `docker login` command.
Performing a `docker login` stores your credentials in plaintext on the client machine. As such, Quay provides the option to use encrypted passwords. This provides you with an encrypted version of your Quay password which can be used on login. Using encrypted passwords ensures that if your client is compromised, the attacker cannot access your Quay.io account directly.
In the event that you lose or forget your password, never fear. You can initiate a password recovery to the email associated with your Quay.io account. Click the "Forgot Password" link on the Sign In screen.
