Earlier quoted context omitted.
You can also add in KeepassHttp + PassIFox. But I wonder if these might have similar vulnerabilities as they too would be handling decrypted passwords.
True, but there are a slew of security issues (and unknowns) with KeePassHttp: https://github.com/pfn/keepasshttp/issues/258 https://github.com/keepassxreboot/keepassxc/issues/147 I've been looking for a alternative with somewhat parity with lastpass with a better security policy.
Cons: NOT open-source, paid cellphone apps.
