The password for the password manager is only in my brain, the only way to get it is to install a keylogger on my machine. If instead I used it on all 30 + websites that requier login the only thing you need to do it is to hack or wait for one of this sites to get hacked and get it from there, then login with it in all this websites. I had used the one password on most websites years ago(I did not known better back then but I did used different password for my important email account), I think my credentials were leacked in 5 data leaks and hackers are still attempting to login with my old credentials in present. The only time this affected me when someone hacked and stole my Minecraft account but I got it back.
