Remember passwords in Microsoft Edge
When you visit a website that requires you to sign in, Microsoft Edge will ask if you want your user name and password remembered. The next time you visit the site, Microsoft Edge will finish filling in your account info. Password saving is on by default, but here’s how to turn it on or off:
In the Microsoft Edge browser, select More actions (…) > Settings > View Advanced Settings.
Turn Offer to save passwords to Off.
Note: This does not delete previously saved passwords. To do that, go to Settings, select Choose what to clear under Clear browsing data, and then choose Passwords.
