Hi ​@Nyhilbo, 

Welcome to Box Community, and we’d love to help regain your Box acces. 

To address the user’s Multi-Factor Authentication, the affected user must contact the Box Product Support team personally to proceed. Please have the user to submit a new case using this link. 

Thanks for posting, and we hope to get this sorted out very soon!

Can someone help me cancel 2FA on one of the external user accounts?Unfortunately, this account can no longer be accessed due to a new phone.

Hi ​@jescsplndd, 

Welcome to Box Community! We already have a related post regarding your MFA inquiry and please do join our discussion!

Disabling the user’s MFA will require account specific verification. We encourage that you have the user to submit a support case. 

Thanks for taking the time, and have a great day! 

I changed my mobile phone number and now I can't approve 2-step verification. What should I do?

Hi ​@yuuuuuuuuuuya, 

Welcome to Box Community! 

Just like what we have suggested above. Since this concerns your Box login, please use the email address associated to your affected Box account and reach out to Box Product Suppor team. 

If you have trouble signing in to the Support page, please use this link. 

Thanks for posting, and we look forward to hear from you!
