I'm also considering using a password manager. At the moment everything is stored on paper and in my mind which is not the best solution.
I rather get one as well considering I only use the save password in my browser which is absurd but without saving the accounts related to money or even important accounts.
Maybe my choice is not what you think but I use 1Password for long periods and has enabled me to sync passwords on my computer and all operating systems easily.
I saw some reviews of this and they're good as well.
However, I'm considering to use lastpass.
Also, since still, no one responds to this question, which is better regarding password managers, a browser extension or desktop app?
