It is improbable. Every password manager on this list uses a powerful 256-bit AES encryption method or equivalent encryption method, so a hacker needs an extremely powerful supercomputer to steal your data. Even so, I probably still can’t access your data, only a random set of data. But, if your master password is weak and can be easily guessed, and you don’t set up two-factor authentication (2FA), you are beating the password manager’s goal. In this case, yes, your password manager can enter (not “hacked” by itself). But if you are using a secure password generator, change the master password every six months and use 2FA, this is unlikely to happen.
