By requiring you to type it twice, the system uses a mathematical comparison to ensure both entries match. If they don't, the system alerts you immediately, forcing a correction before the "wrong" password is saved to the database. When Password Confirmation is Used
When you type a password into a masked field (where you only see dots or asterisks), you can't visually verify your entry. If you accidentally hit "S" instead of "D," you might unknowingly set a password you can never replicate during login.
The most common scenario where a mistake during the initial setup could mean losing access to a brand-new account immediately.
UX designers often debate the necessity of the "Confirm Password" field because it can lead to higher friction and lower conversion rates.
