Trello – How to change the password in Trello

You can't (currently) get the avatar from your google profile. Trello only uses google for signin; it doesn't request access to any of your personal information (e.g. your google profile)

Trello defaults to using your gravatar (if you have one), however you can also upload your own avatar using the following steps:

1. Go to your account page (By clicking your avatar in the upper right corner and clicking "Account", or by going directly to https://trello.com/my/account)
2. Go to the "Avatar" section
3. Here you have three options:
   • Use a gravatar (if you have one)
   • Upload your own avatar
   • Use your initials as an "avatar"

(I've included these instructions since "How do I set or change my avatar" is considered a duplicate of this question)

https://trello.com/my redirects to your account profile. You can see your email address there.

You can see other settings at https://trello.com/my/account.

Per the comments and your edit, the other question is discussed in another place.
