I'd like to change the Gmail address to which Todoist is associated. Is there any way to do this, while retaining all existing tasks?
If you're logging in manually by typing the email/password combination, please click on the gear icon in the top-right corner, go to Settings -> Account and simply edit the email address there.
If you're using a GMail login, then it may also be necessary to deauthorize it in the Settings -> Authorizations section before you change the email address and then authorize the new one through a different GMail account.
How can I change my email address associated with Todoist?
My version 7.0.2 can't permit me to change it, I can' find the possibility to change it.
Is it possible? Thanks
As David said above, you will need to head to the web version (Todoist.com) and sign in from there. Then follow his steps stated above.
