I tried several way to open my "Personal Vault" and it keeps asking for sign in. I use Mac mini Safari.
I can open OneDrive on my iPhone and see all the files in Personal Vault but I can't see it (won't display or open any files)on my Mac mini.
I tried Chrome and still the same response. logged off and back in and nothing.

I reached and see no easy solution.

    Since Personal Vault opens on the iPhone but not on the Mac mini in both Safari and Chrome, focus on the Mac/web sign-in and sync path:

    1. Verify the Microsoft account can sign in normally.
      • Sign in to the Microsoft Account dashboard.
      • If sign-in fails there, use the sign-in helper.
    2. Make sure OneDrive is up to date on the Mac.
      • Install the latest OneDrive version if needed.
    3. Try unlocking Personal Vault again from OneDrive.
      • Select Personal Vault.
      • Complete the identity verification step using the offered method, such as text, email, or Microsoft Authenticator.
    4. If Personal Vault opens but files still do not display correctly, close any files stored in Personal Vault and wait for sync to finish.
      • If sync is slow, increase the auto-lock time in OneDrive: Settings > Account > change the Personal Vault auto-lock time.
    5. If OneDrive itself is signed in but still cannot connect on the Mac, check whether a firewall, VPN, or internet provider is blocking OneDrive.
      • A quick test is to try a different network, such as a mobile hotspot.
    6. Confirm the platform is supported.
      • Personal Vault works with a web browser using the latest version of Microsoft Edge, Chrome, or Firefox.
      • For added security, InPrivate or Incognito mode is recommended.

    If the issue continues after those steps, use Contact Microsoft Support for technical support. On mobile, support can also be contacted by opening the OneDrive app and gently shaking the device.

    Hi!

    Do you have the OneDrive app for Mac? If so, try testing it there.

    A credential or token on your Mac is corrupted. Is your account linked only to browser-based sites, or also to an app on your Mac, such as Microsoft 365?

    Thanks!
    Since Edge is a Microsoft product, it tends to have better compatibility. However, it should work on both Edge and Safari.

    Did you check if there were any pending updates for Safari?

    I was looking into this issue and found that Safari's "Prevent Cross-Site Tracking" feature—and the similar option in Chrome—can cause it. Open Safari, click Settings in the top menu bar > Privacy, then find and uncheck the Prevent cross-site tracking option. Close and reopen Safari, then test it out. You can also check the step-by-step instructions at the link below.
