A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Hi Manoj Rajan,
I hope you remember the email address that you used when purchasing your OneDrive Business plan.
If you do, please follow the steps below:
- Open the Microsoft Authenticator app.
- Click the "+" (Add Account) icon in the top-right corner.
- Select the appropriate account type (Work or School Account or Personal Account).
- Enter your email address and password.
If it is a personal account, your account should be added successfully.
If it is a work account, you will need to contact your company's IT team or Office 365 administrator. They can reset your Microsoft Authenticator registration and help you re-register your device.
Please let me know if you need any assistance with the process.
