I have a bash script which takes in name of the website and generates a 64 character long random string(lower,upper,number,symbol), then puts that in a text file and then encrypts it with gpg using aes256 and puts that file in a dropbox synced directory. Whenever I need to use one, another option retrieves the password, and if I want to use my phone, I just use yet another option which uses qrencode to generate a QR code of the password and then display it using `display` by imagemagick so my phone can scan that to copy the password into clipboard. That's the most safe solution I came up with without trusting third-party solutions. Only downside is dependency on a Linux-powered PC.
