Passkeys are a modern, passwordless authentication method that lets you sign in to websites and apps using your device’s biometric authentication, PIN, or security key. They are designed to be more secure than traditional passwords and are supported by Windows 11, Android, iPhone, macOS, and most modern web browsers. However, some users notice that multiple identical passkeys appear when attempting to sign in to a website, making it difficult to determine which one to use.
This issue can occur if the same passkey has been saved on multiple devices, synchronized through a password manager, duplicated during device migration, or stored by multiple credential providers such as Windows Hello, Google Password Manager, Apple Passwords, or third-party password managers. In some cases, browser synchronization or repeated passkey registration on the same website can also result in duplicate entries.
Fortunately, you can usually resolve the problem by reviewing your saved passkeys, removing duplicate credentials, checking synchronization settings, and re-registering the passkey if necessary. In this guide, we’ll walk you through the most effective methods to fix multiple identical passkeys appearing when signing in to a website.
How to Fix Multiple Same Passkeys Showing Up When Signing In to a Website
Before you begin, determine whether the duplicate passkeys appear only on one website or across multiple websites. Also, identify where your passkeys are stored, such as Windows Hello, Google Password Manager, Apple Passwords, or a third-party password manager. This will help narrow down the cause of the issue.
1. Check Whether the Passkeys Are Stored on Multiple Devices
The same passkey may be synchronized across several devices linked to your account.
- Review the devices signed in to your password manager or cloud account.
- Check whether each device stores the same passkey.
- Try signing in using the passkey associated with your current device.
Multiple synced devices can cause several identical passkey options to appear during sign-in.
2. Remove Duplicate Passkeys
If duplicate credentials have been saved, remove the unnecessary entries.
- Open your device’s passkey or password manager settings.
- Locate the website’s saved passkeys.
- Compare the available entries.
- Delete duplicate or outdated passkeys.
- Keep only the most recent or actively used credential.
Removing duplicates simplifies the sign-in process.
3. Check Your Browser’s Password Manager
Modern browsers can store passkeys independently.
- Open your browser settings.
- Navigate to the Passwords or Passkeys section.
- Review the saved credentials.
- Remove duplicate entries if they exist.
- Restart your browser.
This prevents the browser from offering multiple identical credentials.
4. Review Windows Hello Passkeys
If you’re using Windows 11, Windows Hello may have locally stored passkeys.
- Open Settings.
- Go to Accounts > Passkeys (or the corresponding passkey management section in your Windows version).
- Review the saved passkeys.
- Delete duplicate entries for the affected website.
- Try signing in again.
Managing local passkeys helps eliminate duplicate prompts.
5. Verify Password Manager Synchronization
Synchronization issues can create duplicate credentials.
Check whether you’re using:
- Google Password Manager
- Apple Passwords
- Microsoft Authenticator
- 1Password
- Bitwarden
- Dashlane
Allow synchronization to complete before attempting to remove duplicates.
6. Remove the Passkey from the Website
Some websites allow users to manage registered passkeys.
- Sign in to the website using another authentication method if necessary.
- Open the account security settings.
- Review the registered passkeys.
- Remove duplicate entries.
- Save the changes.
Cleaning up the website’s registered credentials helps prevent duplicate prompts.
7. Create a New Passkey
If duplicate entries continue to appear, recreate the passkey.
- Delete the existing passkey from both the website and your device.
- Create a new passkey.
- Verify that only one credential is registered.
- Test the sign-in process.
A fresh registration often resolves synchronization issues.
8. Update Your Browser
Older browser versions may contain passkey-related bugs.
- Open your browser’s settings.
- Navigate to the About section.
- Install any available updates.
- Restart the browser.
- Test the website again.
Browser updates often improve passkey management and compatibility.
9. Update Windows 11
Microsoft regularly improves passkey support through Windows updates.
- Open Settings.
- Go to Windows Update.
- Click Check for updates.
- Install all available updates.
- Restart your computer.
Keeping Windows updated ensures you have the latest passkey improvements and bug fixes.
10. Disable Conflicting Password Managers
Using multiple password managers simultaneously can produce duplicate passkey prompts.
- Determine which password managers are active.
- Disable or uninstall the one you don’t intend to use.
- Restart your browser.
- Test the website again.
Using a single credential provider reduces confusion and duplicate entries.
11. Clear Browser Cache and Site Data
Corrupted website data can occasionally affect authentication.
- Open your browser settings.
- Navigate to Privacy.
- Clear:
- Cookies
- Cached images and files
- Site data for the affected website
- Restart the browser.
- Sign in again.
This forces the website to establish a fresh authentication session.
12. Contact the Website’s Support Team
If duplicate passkeys continue to appear despite cleaning up your credentials, the issue may lie with the website’s implementation.
Provide the support team with:
- Your browser version
- Operating system
- Device type
- Screenshots of the duplicate passkeys
- Steps to reproduce the issue
They can determine whether the problem is related to the website’s passkey implementation or account configuration.
Conclusion
If multiple identical passkeys appear when signing in to a website, the issue is usually caused by synchronized credentials across multiple devices, duplicate registrations, multiple password managers, or browser synchronization problems. In most cases, removing duplicate passkeys, reviewing your password manager, updating your browser, and re-registering the passkey will resolve the issue.
If the problem persists, update Windows 11, clean up the passkeys stored on both your device and the website, and ensure you’re using a single credential provider whenever possible. Keeping your browsers, operating system, and password manager up to date will help ensure a smoother and more reliable passkey sign-in experience.
