Multi-factor authentication (MFA) enhances website security by requiring additional authentication steps, such as a one-time passcode, to protect against threats like leaked credentials and guessed passwords. However, it can cause user frustration due to the extra steps required for each login. To mitigate this, a "remember my device" feature can be implemented, which skips MFA for familiar devices over a set period. This trades some security for convenience, being suitable for most scenarios except those needing high security, like financial transactions or accessing sensitive systems. The implementation can use browser cookies or device identification, with the latter offering more persistent and versatile identification. The tutorial details using Fingerprint's device intelligence to add a "remember my device" option to an MFA-enabled app, leveraging device identifiers to skip MFA for devices recognized within the past 14 days. This approach aims to balance security with user experience by reducing frequent MFA prompts while maintaining adequate protection against unauthorized access.
