This is a brief description of my security practices. I will make several posts and write updates as I make changes.
For password mangement I use LastPass. LastPass has its issues, however it is, in my opinion, the best balance of convenice and security. It encrypts all passwords and syncs the encrypred file to all computers and is only decrypted locally. It has only had two suspected breaches in its history and the company disclosed them and corrected them quickly.
I use the LastPass password generator for all sites. So each site has a long alphanumeric password that is unique. I only memorize my master password and a few other high value ones (like my Google account). I also protect login to my account with two-factor authentication.
I use their browser extension and Android and iOS apps to get my passwords when I need them.
This is the part of my setup I am the least comfortable with. LastPass has a good history, but my passwords are completely in the hands of a proprietary peice of software that hasn't been audited. I obviously trust it enough to use it, but I wish there was an equivalent piece of open source software.
