You can reset your password by going to https://id.atlassian.com/login/resetpassword. If your email address is not associated with an existing Trello account, we'll let you know after you submit the form.
Using the above link should take care of most cases where you can't access your account. However, sometimes things can get a bit complicated. We'll address each scenario individually.
Verifying your account
We have only two ways to verify that you are the owner of your account:
You know the email (or username) and password of your account and can log in at trello.com.
You own the email address associated with your account and can recover your password at https://id.atlassian.com/login/resetpassword.
NOTE: If your account was created via Google log-in, you will also be able to recover your Trello account by logging in via your Google account.
Because these are the only two methods to verify your account, it is critically important that you keep your email address up to date. If you change jobs, graduate from college, etc. and no longer have access to the original email address you used to access Trello, you may not be able to recover your account if you forget your password.
You are not receiving password reset emails
If you're using the password reset form, but not receiving the emails, please see Not receiving confirmation emails or password reset emails.
You don't use that email anymore
You may no longer have access to the email address associated with your account. This happens sometimes when you change jobs and aren't using your work email anymore. This can also happen if you delete your email account.
For security reasons, we are not able to change the email address on your account (see below). Your best bet is to contact your former employer directly and ask if they can help you reclaim your Trello account by temporarily re-opening your old email account.
Why can't you change my email address?
For security reasons, we cannot change the email address associated with your account. If we were allowed to change your email address, this would expose your account to "social hacking." Social hacking is when someone pretending to be you sends us an email asking us to change the email address associated with your account, thus giving the hacker control of your account.
For example, let's say your name is Robert Jones and your work email is firstname.lastname@example.org. Someone could create a fake email address, e.g. email@example.com, and email us, pretending to be you. They might say how they changed jobs and no longer use firstname.lastname@example.org and could we please change the email for them. We cannot.
The Trello team cannot change the email address associated with your account.
