I think this is a duplicate question but am not able to mark it as such.

This should work, taken from the bcryptJS docs .

Sync

// Load hash from your password DB.
bcrypt.compare(myPlaintextPassword, hash, function(err, result) {
    // result == true
});

Promise

// Load hash from your password DB.
bcrypt.compare(myPlaintextPassword, hash).then(function(result) {
    // result == true
});
