Changing the admins of a team or board
See Adding an admin to your team if you are already an administrator of your team and wish to add additional administrators.
This article is intended to be used by people who need to recover a team or board when one of the administrators leaves the company. The article is written with teams in mind, but it also applies to administrators on a board as well.
Options for changing admins when the only admin leaves
When there is only one admin of a team and that person leaves or is no longer using Trello, there is a loss of continuity in administering the team in Trello. While this situation is not ideal, you have several options to reclaim ownership of the team, the boards, and/or the data on the boards.
1. Upgrade to Business Class
If you need to recover a board, and that board belongs to your team, you can upgrade your team to Trello Business Class, which adds several features to make managing teams a bit easier, including the ability for team administrators to take control over all boards in the team. You can sign up for Business Class here: https://trello.com/business-class (Note, you must be a team admin to upgrade to Business Class).
2. Recovering an account by password or email address
Another option if the user's associated email address is a company email address (e.g., firstname.lastname@example.org), you probably have access to their inbox by way of your email management system administrator. Trigger a password reset at https://trello.com/forgot and reset their password, then log into their Trello account. Then, make yourself admin over the boards in question. After that, log in as yourself and remove the user from the boards (and maybe make a couple of team members admin over those boards to avoid this situation in the future).
3. Check to see if there are other administrators
There may already be more than one admin for your team. You can check by visiting your team page in Trello and looking for the admin indicator on the avatars of your members. See Presence and admin indicators on user avatars to see what the admin indicator looks like. If there is already another administrator, contact them about setting up additional admins.
4. Contact the former administrator
If you are able to contact the admin who left the team, ask them to log into Trello and add you as an administrator of the team. Once you are an administrator, you can make any changes you wish
"Can you make me the admin for this team?"
For security reasons, we are unable to modify the administrators of a team or delete a team. See Why Support can't grant access to your account for a detailed explanation.
If you're not able to change admins after the previous admin leaves
If the only admin is no longer affiliated with your team, you're unable to contact them, you don't know their password, and they were not using a company email address for their Trello account, you will not be able to gain control of the team. If this is the case, these steps can help you get going with a new team.
1. Set up a new team
If you're not able to gain admin access to your previous team, you can create a new team in Trello and set up admins for the new team as appropriate.
2. Set up multiple admins
When you have multiple administrators for your team, you lower the risk of losing continuity of control when an administrator leaves the company or team. See Get the most out of Business Class for more best practices about setting up and maintaining your team. Although the content is specifically geared towards those teams with Business Class, the concepts about team management apply to all teams.
3. Move the boards from the old team to the new one
Even if you are not an administrator of the old team, you may still be admin of boards within that team. If so, you can change the team to which a board belongs to move existing boards to the new team.
4. Copy any boards you're not able to move to the new team.
If you're a normal member of a board (but not an admin), you can copy the board and then add the copied board to the new team. Optionally, you may wish to delete cards from the board that belongs to the old team. Another option is to create a new board, and then move each list from the old board to the new one. Unlike copying a board, this will preserve the comments and history of the cards.
5. Canceling Business Class
If you are an admin of your team, you can cancel Trello Business Class via the link at the bottom of your team's billing page.
If you are not an admin of the team (or no longer have access to the team), the most direct approach is to contact another admin in the team and ask them to cancel Business Class.
If you are not an admin of the team, are unable to contact another admin to cancel, and wish to cancel Business Class so that your credit card is no longer charged, please contact Trello support. While we are unable to grant control of the team by adding additional admins, we can cancel Business Class on your behalf. Some proof of purchase may be required. The team won't lose any data when Business Class is cancelled.
