Trello – How to Merge Two Accounts

There isn't a way to collapse boards together.

There have been a lot of requests for a view that combines all your cards across all boards. There is a card for it here: https://trello.com/c/UOIrt48P

It's generally not necessary to merge accounts in Trello. In these situations, there's almost always a more-used and less-used account. The real difficulty usually happens when people invite your less-used account to their board. So you just really want to get rid of that account. Here's how to do it.

1. Log into your less-used account.
2. Invite your more-used account to each board owned by the less-used account.
3. Make your more-used account an admin over each board.
4. Leave each of your boards. (You may have to make yourself a non-admin.)
5. Delete your account by going to https://trello.com/my/account and going to the bottom of the page and clicking the Delete link.

That's it!
