What is the purpose of re-entering the password?

The purpose of re-entering the password is primarily to confirm that it was entered correctly. This step is crucial because it helps to prevent errors that can occur when typing, such as mistyping a letter or number. By asking the user to enter the password twice, the system ensures that the password they intended to use is accurately captured.

This verification process is a common practice in many applications and platforms, as it helps to reduce the chances of access issues that might arise from a simple typing mistake. The other options may involve aspects of password management or security, but the core reason for this step is to ensure that the user has correctly communicated their desired password.
