Don't store your passwords anywhere, have them be determined by generating a unique password based on the service name and a master password with an added salt, this is similar to other proposed algorithm methods except more secure because your unique salt is used in addition to your master password, so even if someone guessed/learned your master password (e.g. social engineering) they would not be able to generate the same result passwords for services without your unique salt that's only located on your device(s) which should (hopefully) be physically secure. This way you only need to remember one password (master) to re-generate your password for any given service, and nobody can replicate the resulting service passwords without knowing BOTH your master password and your salt. I wrote a proof of concept a few years ago, it's pretty outdated and generating word phrases would be better than just hashes, but it conveys the idea: https://github.com/wyqydsyq/ysnp https://github.com/wyqydsyq/ysnp
