Ever since the Lastpass breach (thankfully moved to Bitwarden and recycled passwords prior) I've had a heightened awareness of the potential for vulnerabilities beyond my paygrade leading to online catastrophe for me. I use Bitwarden to generate a random password for all sites.
If it's something which could truly cause a headache such as my email or banking however, I'll usually append the domain name, or a word, or a symbol to the password such that after my phone or PC's Bitwarden autofill enters the saved password I also need to enter whichever word or symbol for the site. Feels like this gives me some defense if people smarter than me made a mistake, but I guess I have questions for folks who know about hashing/blackmagic/thecyber.
- Would this have any benefit, if one were to put "google" at the end of their Google password, as far as protecting from a password manager exploit?
- No, I don't actually put google or reddit at the end of my password; oops not a question
- Is that already something baddies would know to try? Or did I just play myself by posting this on the internet?
Yes, it is something "baddies" would know to try... but most likely wouldn't.
Your passwords are at risk from:
Your strategy only enhances your security in case 4, where someone would somehow manage to get your unique site password without compromising your system.
Otherwise, you're compromised with or without it: in cases 1 and 2, it's your fault; cases 3 and 5 are basically the same case, you've got your system compromised and the attacker can capture whatever you type; in case 6, you're in bigger trouble already.
The likelihood of case 4, is relatively low, since the other cases are easier and/or more effective.
