I use LastPass since several years, most of info is there and it would be hard to migrate it. How reliable are these pwd managers, especially the ones who store info on their servers?
IIRC, lastpass uses aes-256 encryption, and apparently your key never leaves your local system (the encryption should happen on your system before the encrypted data is sent to lastpass). If this is true, their security model would be reasonably safe...
However, i would NOT use an online password manager for keeping seed phrases or private keys... But that's just my personal opinion... I would never store something that important on a cloud server, no matter how good their scheme is... If somebody gets their hands on your master password, or if your browser is compromised, or if you fall victim to a MITM, or if the encryption scheme is ever broken your passwords are up for grabs...
Also, this is just lastpass, it does not mean other online password managers are equally safe... And i did not check lastpass'es sourcecode, so i'm just believing what they tell me...
