Hello,
In our Jira cloud we have one of the unmanaged user lost his MFA Device and he is unable to login to Jira as it requires 2 step-verification.
FYI, we have enforced 2- step verification option under security, authentication policies and we disable this option due to security reasons.
user does not have recovery key with him so what are the possibilities for the user recover his account / login to application.
Let us know if you need any additional information from ourside.
Thanks
