We (a software company) allow clients to participate by commenting on Jira issues.
One of our clients has changed positions (new workplace), but still need to access his account and view issues. However, I cannot change his email address, even as an administrator. I can only "suggest changes". This means a mail is sent to his old address, which then (after much work) has been reopened and the mail is then forwarded to his new address.
But now the trouble starts; he had 2FA enabled and then removed the entry in the authentication app.
So when he receives the email with the suggested changes, he's asked to log in, which he can't, because of the 2FA.
How come I - as an administrator - simply cannot change his email address for him?
All suggestions are welcome!
