If you're facing errors while using Microsoft Authenticator's passwordless sign-in, you're not alone. Common issues can often be resolved with straightforward troubleshooting steps, allowing you to regain access quickly. This guide outlines frequent error messages, their meanings, and effective solutions.

## What errors are you seeing?

Common error messages you might encounter include:

```text
Error: "Something went wrong. Please try again later."
Error: "Unable to complete sign-in."
Error: "Authentication failed."
```

These messages typically indicate problems with connectivity, app configuration, or account settings. If you see these errors, it usually means your device is struggling to communicate with Microsoft's servers or there is a configuration mismatch.

## When does this issue occur?

Passwordless sign-in errors can arise in several situations:

- **Device changes**: If you've recently switched devices or reinstalled the app, it might not be configured correctly.
- **App updates**: Updates can sometimes result in temporary compatibility issues.
- **Network issues**: An unstable internet connection can lead to sign-in failures.

## Before you start

This guide applies to the Microsoft Authenticator app on both iOS and Android devices. You will need administrative privileges to modify app settings. Before troubleshooting, ensure your device is connected to a stable internet connection and that the app is installed and set up correctly.

## How to troubleshoot your sign-in error

Follow these steps to resolve common passwordless sign-in errors:

1. **Check your internet connection.** Ensure you have a stable connection.
2. **Restart the Microsoft Authenticator app.** Close and reopen the app to refresh the session.
3. **Reconfigure your account in the app.** Go to settings and remove your account, then re-add it. \`\` `text Settings > Accounts > Remove account > Add account `\`\`
4. **Update the app.** Confirm that you're using the latest version of Microsoft Authenticator by checking your app store for updates.
5. **Check device settings.** Make sure notifications are enabled for the app, as this can affect sign-in prompts. \`\` `text Settings > Notifications > Microsoft Authenticator > Allow Notifications `\`\`

If the issue persists after these steps, consider resetting the app settings as a last resort.

## How to verify your sign-in is working

After troubleshooting, verify your passwordless sign-in by:

1. **Attempt to sign in again** using the Microsoft Authenticator app.
2. **Check for a successful notification** on your device. You should receive a prompt to approve the sign-in.
3. **Confirm access to your account.** If you can log in successfully without entering a password, the issue is resolved.

## Tips to avoid future sign-in errors

To prevent future passwordless sign-in errors, consider these best practices:

- **Keep the app updated.** Regularly check for updates to maintain compatibility.
- **Maintain stable internet connectivity.** Use a reliable network to avoid interruptions.
- **Backup your account settings.** Utilize app features to back up your settings for easier recovery if needed.
- **Enable two-factor authentication.** This adds an extra layer of security and can help prevent issues related to account access.

## Conclusion

If you continue to experience issues despite following these steps, it may be beneficial to contact Microsoft support for further assistance. Keeping your app updated and ensuring stable connectivity can significantly reduce these errors in the future. Don't hesitate to revisit these troubleshooting tips if problems arise again.
