Hello,

I got a similar issue, MFA was activated on my coworker account and he doesn't have the device to get the code.
I'd be grateful if someone could help me deactivating MFA on his account.

He was able to get in touch with the support following this : https://support.box.com/hc/en-us/community/posts/11937423038355-Remove-MFA
Hope it can help.

Hi Aiki, 

Welcome to Box community!

In case your co-worker encounters trouble logging into box.com due to account authentication, please tell her to submit a support ticket and ask for an MFA reset.
