Gmail - App Specific Passwords
If you're a Gmail user, you will want to create an app specific password whenever you are setting up credentials for an application. For me, this is most commonly when I want to configure applications such as Gitlab to be able to send emails, using my gmail account, but it can also be in situations such as setting up thunderbird to act as your email client.
By creating randomly generated passwords for each individual application, you can easily revoke permission later from the admin area without worrying about having to change your password and re-configure all your other accounts with the new password.
