I love bitwarden - but there are many ways my passphrase might be compromised. This is a little alliveated by 2fa - but unless the 2fa comes from a second hw device, there's almost complete overlap between threats that compromise my passphrase (for bitwarden) and my 2fa secret (in bitwarden or another 2fa app)...
