Question details

The user forgot the four-digit passcode for the OneDrive iOS app or Personal Vault and needs to reset it to regain access to their files.

How to Reset OneDrive Secure Vault Passcode on iPhone
Product
Microsoft OneDrive
Device & OS
iOS (iPhone)
Scenario
Attempting to access OneDrive files through the iOS Files app or opening the Personal Vault when the four-digit passcode is forgotten, even if Face ID is still active.
Observed behavior
The iOS Files app strictly requires the four-digit passcode to access OneDrive files. A standard Microsoft account password reset does not reset this specific local app passcode, leaving the user locked out of the vault.
Before you start

Ensure you have your main Microsoft account credentials (email and password) ready, as you will need them to verify your identity after locking out the current passcode.

Solution 1Recommended

Force Sign-Out by Entering Incorrect Passcode

This is the most direct method to reset the passcode by triggering OneDrive's local security lockout, allowing you to re-authenticate and create a new passcode.

When you repeatedly enter an incorrect passcode, the OneDrive app eventually assumes an unauthorized access attempt and forces a complete sign-out. This clears the forgotten passcode and allows you to set up a new one upon signing back in.

1
Trigger the Passcode Prompt

Open the OneDrive app or attempt to access your OneDrive files via the iOS Files app so that the four-digit passcode screen appears.

2
Enter Incorrect Passcodes

Repeatedly type in an incorrect four-digit passcode until the app locks you out and automatically prompts you to sign in with your Microsoft account.

3
Verify Your Identity

Sign in using your main Microsoft account password to verify your identity and regain access to the app.

4
Create a New Passcode

Tap on your Profile picture, navigate to Settings, select Passcode, and follow the prompts to create a new four-digit passcode and re-enable Face ID.

Force Sign-Out by Entering Incorrect Passcode
Important Distinction: This process only resets the specific app and Personal Vault passcode on your iPhone. It does not change or reset your main Microsoft account password.

Frequently Asked Questions

Does resetting the OneDrive Vault passcode change my Microsoft account password?

No, the four-digit passcode is specifically for local access to the OneDrive app and Personal Vault on your iPhone. Resetting it does not affect your main Microsoft account credentials.

Why doesn't Face ID bypass the passcode in the iOS Files app?

While Face ID may work seamlessly within the standalone OneDrive app, iOS integration through the native Files app sometimes strictly requires the manual four-digit passcode for elevated security when accessing third-party vaults.

Will I lose my stored files if I uninstall the OneDrive app?

No. Your files are safely stored in your Microsoft cloud account. Reinstalling the app only clears local app settings and security preferences, not your uploaded data.
