LastPass. It's good enough and worth the US$12/pa.

Syncs with Linux & Android. Lets me easily share passwords where needed. Has 2FA.

Literally renewed today. I did take a look at LessPass [sic] and a few others - I'd prefer an open-source and self hosted solution, but LastPass is cheap enough and convenient not to make it a priority.

That said, I do have a few sites which I use my own self generated password - makes logging in on, say, smart TVs a bit easier. I use the same "algorithm" for each - for example, for Twitter, TWpass321.

The other line of defence is a unique email address for each service. Using a catch-all email means I can be twit@example.com, bing@example.com, etc.

If one if those services are compromised, I know exactly who has leaked my details - and they can't use those credentials to log into another service.

I have a perl script that I type a pass phase into, as well as the domain name of site, and it uses a hash function to create a password.

On average the password is rich in upper case, lower case, symbols, etc. Sometimes though it lacks a number or has a character that is not allowed, and the adaptations to that are another part of the story.

I have thought of making a little JS app that runs on a web browser but haven't done it out of paranoia.

KeePass, secured with password + private key. The private key is not synced to the cloud, but the KeePass database is synced with SpiderOak. OwnCloud would be better for that, though.

I will never touch anything like LastPass, Dashlane, etc., where you have no idea how secure anything is.

MacOS’s keychain, and LastPass.

Up voted, and seconded. Last pass is great for group sharing as well.
