How to Use a Different Authenticator App for OneDrive 2FA
Question details
The user wants to use a third-party authenticator app instead of the default Microsoft Authenticator for securing their OneDrive and Microsoft account.
- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Setting up Two-Factor Authentication (2FA) for a Microsoft account.
- Observed behavior
- The setup process heavily promotes Microsoft Authenticator, making it unclear how to select and configure a different compatible authenticator app.
Ensure you have your preferred authenticator app (such as Google Authenticator, Authy, or Duo) installed and updated on your mobile device before starting the setup process.
Select the Alternative Authenticator Option During Setup
Bypass the default Microsoft Authenticator prompt by clicking the specific text link to use a different app during the 2FA setup process.
Microsoft strongly encourages users to adopt its proprietary authenticator app by making it the most prominent button on the screen. However, they still fully support industry-standard TOTP (Time-based One-Time Password) apps. You just need to know where to click to reveal the standard QR code.
Log into your Microsoft account security dashboard, navigate to the advanced security options, and choose to turn on two-step verification or add a new way to sign in.
When the prompt appears urging you to download Microsoft Authenticator, ignore the main button. Instead, look for the smaller text link that says 'Set up a different Authenticator app' and click it.
Open your preferred authenticator app on your smartphone, select the option to add a new account (usually a '+' icon), and scan the QR code displayed on your computer screen.
Type the 6-digit code generated by your third-party authenticator app into the Microsoft setup page and click verify to complete the configuration.

Frequently Asked Questions
Which third-party authenticator apps work with Microsoft accounts?
Most standard TOTP (Time-based One-Time Password) apps are fully compatible. Popular choices include Google Authenticator, Authy, Duo Mobile, and password managers with built-in authenticators like 1Password or Bitwarden.
Why does Microsoft keep prompting me to use their authenticator app?
Microsoft defaults to promoting its own ecosystem apps for integrated security features like passwordless sign-in and push notifications, but they continue to support standard third-party authenticators via the 'Set up a different Authenticator app' link.
Can I use multiple authenticator apps for the same Microsoft account?
Yes, you can configure multiple authentication methods in your Microsoft account's security dashboard. Alternatively, if you scan the setup QR code simultaneously with two different authenticator apps before clicking next, both apps will generate valid codes for the same account.
What happens if I lose access to my third-party authenticator app?
If you lose access to your authenticator app, you will need to use an alternative verification method, such as an SMS code, secondary email, or the recovery code generated when you first set up two-factor authentication.
