Provide security of user data

Offering users the convenience of remembering their login credentials can make the experience smoother. On platforms where repeated entry is common, this feature can cut down on user frustration significantly.

However, for websites where the stakes are high in terms of security, like banking or healthcare platforms, there's a need to strike a balance. While it may not be advisable to keep users always logged in, you can offer to remember their username. This speeds up the login process without compromising security.

To bolster this approach, consider implementing an additional layer of authorization, such as two-factor authentication (2FA). When users attempt to log in, a unique code could be sent to their registered email or phone number, ensuring that the person attempting to log in is indeed the account owner. This allows for a blend of convenience and security that enhances the overall user experience.
