Monthly fee for everyone or you mean freemium? Freemium in my opinion wont be enough to cover the cost, because works well only with services with low cost per-user. And monthly fee for everyone is a very hight incentive of not using YouTube.

It shouldn’t be possible to break any service but hackers do that daily. If proper security is in place they will need some 0day exploits, but it’s not impossible, just extremely difficult

I know, but that won’t change the eventuality I described

Bro, what I said is that an attacker who someways get access to production, can push modified source code that send cleartext password to him before everything else.

If someone compromise bitwarden infrastructure can (and probably will) silently release a “new” minor version of app and webapp so that every master password is sent to him, and then decipher passwords.

It will last only some hours at worst but will still collect a lot of passwords.

That’s only thing I’m worries about, but I still use bitwarden as I think my passwords being compromised in this evenience as nearly impossible
