I can't log in into my Microsoft teams

Hi @EZATTUL NAJIHA BINTI ABDULLAH,  

Thank you for posting your question in the Microsoft Q&A forum.         

I'm sorry to hear about the difficulties you're experiencing accessing your Microsoft professional account due to the loss of access to the Authenticator app. 

Unfortunately, in cases like this, where no alternative authentication methods were set up, Microsoft Support is unable to directly assist with account recovery. This is because your account is managed by your organization, and only your IT administrator or support team has the necessary access and authority to reset authentication settings or provide alternative login options. 

Please contact your organization's IT department or system administrator and explain the situation. They will be able to: 

• Reset your multi-factor authentication (MFA) settings. 
• Provide a temporary access method. 
• Help you reconfigure the Authenticator app on your new device. 

If your IT team needs any guidance from Microsoft, they are welcome to contact us through their designated support channels. 

Thank you again for reaching out, and please let us know if there's anything else we can assist you with. 

Warm regards,
