The 'Token expired' message can occur when going through the process to set/reset your password.
When you have requested the new password link, you have to click on the latest link to your inbox within about 5 minutes, so that it doesn't expire.

This means that if you click on the first link, after requesting the second link, this will no longer be valid (hence, "expired").
Please request a new password reset link again, and await for this to come to your main inbox or junk mail.
The message will look like this:
