Hi @Shailesh Patel ,
Do you mean you have typed the verification code you received but cannot sign in Teams client?
Does this issue happen in Teams desktop client or Web client?
According to your description, it seems you have enabled 2FA in Office 365. In this case, we recommend you try to follow these steps to disable multi-factor authentication:
- Go to the Office 365 admin center.
- Go to Users > Active users.
- Click on Multi-factor authentication tab option (in new admin center).
- Select your user
- Click Disable on the right side.
