Safari making up and storing new, wrong passwords?

[IndyMac]

On my Macbook with Ventura 13.5.2 I noticed Safari is making up additional incorrect passwords for sites I visit. So if I have a password for somesite.com with the username John Smith it will add additional entries with wrong passwords. When I go to sign it, it shows lots of login options.
I have cut off autofill, but it's still happening and it is syncing to my iPhone as well. Ran a virus / malware scan on my computer. Nothing shows up. It's almost like it is making up strong passwords for every site and not stopping. I can erase them, but the process starts again.

1. Any idea what is happening and why?
2. Is this happening through iCloud or something to sync it to other devices?
3. How do I stop this?

Thanks. Can't find anything online about it.

Hello and welcome.

Sorry for the delayed response.

Sounds like iCloud Keychain may be activated. Normally, it will only store passwords that you create and save and not create and add them automatically. You can check in the following to edit/remove any extra passwords:

• Safari > Settings > Passwords
• Macintosh HD > Applications > Utilities > Keychain Access

Set up iCloud Keychain to autofill information on Mac
Manage passwords using keychains on Mac
