Salts ensure identical passwords produce different hashes, defeating rainbow table attacks. During registration, passwords are salted and hashed before storage. During login, the stored salt is retrieved, applied to the submitted password, and the resulting hash is compared. Additional security measures include rate limiting, account lockout, adaptive hash parameters, and optional pepper keys stored outside the database. ## Full article daily.dev links to this article rather than hosting it.

Stronger, more secure, even tho it uses slightly more memory to do its tasks. Not something anyone would notice tho. **@jake\_nerdnest** · 0 upvotes > don't.
