Is password hashed in frontend or backend?
The backend.
If you only hash them in the frontend, you are vulnerable to a pass the hash attack. The reason that you hash passwords in your database is to prevent an attacker who already compromised your database from using those passwords.
How do hackers find hashed passwords?
The problem is that the hashes still have to be stored, and anything that is stored can be stolen. Hackers could get the password hashes from the server they are stored on in a number of ways. These include through disgruntled employees, SQL injections and a range of other attacks.
Can you decode a hashed password?
Hash functions are designed to go only one way. If you have a password, you can easily turn it into a hash, but if you have the hash, the only way to get the original password back is by brute force, trying all possible passwords to find one that would generate the hash that you have.
Should passwords be hashed on client side?
Hashing passwords makes it possible to use them for authentication, while making it hard to reconstruct the original password. Hashing passwords on the client may be beneficial: even though it does not protect against attackers, it does protect against accidental mistakes.
