Might be an interesting thread to read.
Many says that your system is “better than the average person reusing the same password”, but still not better than a password manager, and that you can’t “out remember a machine”. Many have also pointed out that data breaches and hacking is actually very common these days, all an attacker would need is 2 sample and they would see the pattern; On top of that, with the development of AI, there could eventually be a bot that would to test variations of jusr one leaked password and attack your acounts on different websites, then you’d have to change all your passwords, instead of just one. Someone also said that, this is essentially like a Master Password of a password vault + a “Salt” as your passwords, and the password is only as secure as those few unique characters, which could be cracked very easily.
