When I log into my web browser I typically utilize Norton Password manager. Norton monitors for compromised passwords and alerts you if it sees your password come up on a list of compromised passwords (password is saved in Norton secure Vault).
In my case, the first time I saw this I changed my password to a randomized 16+ character jumble of characters, symbols, numbers, etc, but I still get the warning. This doesn’t happen with any of my other accounts and I don’t repeat passwords. Any thoughts on why this may be happening?
