Hi, I'm John! I will help you with this.
First, Edge only syncs passwords to the Microsoft account that was signed in at the time. Can you check if you’re currently signed in with the same Microsoft account you used before the passwords disappeared?
You can check this by opening Edge > clicking your profile picture in the top-right > and looking at the email shown there. If it’s different from your usual account, try signing back in with the original one.
If the correct account is signed in, please check if sync was turned off:
- Go to Settings (three dots > Settings).
- Select Profiles > Sync.
- Make sure Passwords is enabled.
If sync was disabled earlier, the passwords might still be saved locally. You can check here: edge://passwords Just paste it in your address bar.
If issue persists, if the passwords don’t appear in sync or locally, please let me know if you recently reset Edge, reinstalled Windows, or changed accounts.
