How Does Facebook Save Users' Passwords?

Facebook encrypts and hashes users' passwords to securely store them in their database. When a user creates an account or changes their password, Facebook uses a strong cryptographic hashing algorithm to convert the password into a long string of characters, which is then stored in the database.

Additionally, Facebook employs salting, a technique where a random value is added to each password before hashing. This adds an extra layer of security by ensuring that even if two users have the same password, the hashed versions will be different due to the unique salt.

Moreover, Facebook continuously updates its security protocols and conducts regular security audits to protect users' data from cyber threats and unauthorized access.
