almost a year update: my current password manager is bitwarden with a self-hosted server. your vault is encrypted and it's open-source so anyone can verify this. https://twitter.com/reeseovine/status/1267480310062727171

my server uptime isn't great but each client stores a local copy so that you can still use it offline; it just won't sync with other clients until the server is online again.

i chose to self-host for the premium features and for the security of knowing i own my data.

it has a really powerful password generator where you can choose the length, how many numbers and/or special characters it has, and whether to avoid ambiguous characters so it's easier to type it somewhere else.
it can also generate passphrases!
