Hi Florent, welcome to the community!
Sorry to hear about that! It looks like you have the 2-factor authentication enabled and can't log in to Trello.
If you have access to the mailbox you would be able to regain access to your account. Please check the steps below:
- To sum up, try to log in, you will see the image below, and click on *Can’t use your phone?*
- Then click on *Can’t find your recovery key*
- Select Send recovery email. An email will be sent with more information with the subject line Steps to recover your Atlassian account.
*Note:* This email does not contain the one-time link yet.
After those steps, you will get a *second email in 24 hours* with instructions to remove the 2FA.
Make sure you are available to check your inbox 24 hours after the first email is sent as the link in the second email will expire if not used in time.
The completed article, you can see here: https://support.atlassian.com/atlassian-account/docs/login-issues-related-to-two-step-verification/
Hope this helps!
