This additional layer of security significantly reduces the risk of unauthorized access, even if a password is compromised. 2FA combines something the user knows (like a password) with something the user has (like a mobile device) or something the user is (like a fingerprint), making it much more difficult for attackers to gain unauthorized access. ## How it works Two-Factor Authentication typically works as follows: - Initial Login: The user enters their username and password. Second Factor Request: After successful password verification, the system prompts for a second form of authentication. Second Factor Provision: This can be: * A code sent via SMS or email * A code generated by an authenticator app * A push notification to a registered device * A biometric factor like a fingerprint or face scan - Verification: The user provides the second factor. Access Granted: If both factors are correct, access is granted. - Types of 2FA factors: - Knowledge: Something you know (password, PIN)4 - Possession: Something you have (phone, security token) - Inherence: Something you are (biometrics) - Location: Somewhere you are (GPS location) ## Relevance For Flowdrive, implementing Two-Factor Authentication is crucial for securing [File Hosting](https://tryflowdrive.com/glossary/file-hosting) services: - Account Protection: 2FA significantly reduces the risk of unauthorized access to user accounts, even if passwords are compromised. - [Data Encryption](https://tryflowdrive.com/glossary/data-encryption) Complement: While encryption protects data, 2FA ensures only authorized users can access the decryption keys. - [API](https://tryflowdrive.com/glossary/api-application-programming-interface) Security: 2FA can be integrated into API access tokens, enhancing security for programmatic access. - Compliance: Many regulatory standards require or strongly recommend 2FA, helping Flowdrive meet compliance requirements. - [User Permissions](https://tryflowdrive.com/glossary/user-permissions) Enhancement: 2FA adds an extra layer of verification before granting access to sensitive files or admin functions. - Trust Building: Offering 2FA demonstrates Flowdrive's commitment to security, building user trust 2FA works alongside other security measures like [SSL TLS](https://tryflowdrive.com/glossary/ssl-tls) and [HTTPS](https://tryflowdrive.com/glossary/https) to create a comprehensive security framework. It's particularly important for protecting accounts with access to sensitive files or administrative capabilities. ## Examples - A Flowdrive user enables 2FA, requiring them to enter a code from their authenticator app in addition to their password when logging in. - An administrator accessing Flowdrive's management console is required to approve a push notification on their registered device after entering their credentials. - A developer using Flowdrive's [API](https://tryflowdrive.com/glossary/api-application-programming-interface) generates a secure access token using 2FA, ensuring that even if the token is exposed, additional verification is required for use. ### Navigation [Previous Static Site](https://tryflowdrive.com/glossary/static-site) [Next User Permissions](https://tryflowdrive.com/glossary/user-permissions) ### Tags & Share Share this glossary svg]:pointer-events-none [&>svg]:size-3 text-foreground bg-white border [a&]:hover:bg-accent hover:border-primary [a&]:hover:text-accent-foreground cursor-pointer rounded-full transition-colors hover:bg-primary hover:text-white">securitysvg]:pointer-events-none [&>svg]:size-3 text-foreground bg-white border [a&]:hover:bg-accent hover:border-primary [a&]:hover:text-accent-foreground cursor-pointer rounded-full transition-colors hover:bg-primary hover:text-white">authenticationsvg]:pointer-events-none [&>svg]:size-3 text-foreground bg-white border [a&]:hover:bg-accent hover:border-primary [a&]:hover:text-accent-foreground cursor-pointer rounded-full transition-colors hover:bg-primary hover:text-white">access controlsvg]:pointer-events-none [&>svg]:size-3 text-foreground bg-white border [a&]:hover:bg-accent hover:border-primary [a&]:hover:text-accent-foreground cursor-pointer rounded-full transition-colors hover:bg-primary hover:text-white">identity verificationsvg]:pointer-events-none [&>svg]:size-3 text-foreground bg-white border [a&]:hover:bg-accent hover:border-primary [a&]:hover:text-accent-foreground cursor-pointer rounded-full transition-colors hover:bg-primary hover:text-white">account protection Share on social media Related terms [SSL/TLS](https://tryflowdrive.com/glossary/ssl-tls)[HTTPS](https://tryflowdrive.com/glossary/https)[User Permissions](https://tryflowdrive.com/glossary/user-permissions)[Cloud Backup](https://tryflowdrive.com/glossary/cloud-backup)[OAuth](https://tryflowdrive.com/glossary/oauth) ### Start hosting for free Unlimited file hosting for Webflow projects. svg]:px-2.5 w-full" type="button">Get Started svg]:px-2.5 w-full shadow-none" type="button">View plans ## Related articles Continue reading with these related articles on similar topics. ### SSL/TLS SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols that provide secure communication over a computer network. ### HTTPS HTTPS (Hypertext Transfer Protocol Secure) is an extension of HTTP that uses SSL/TLS for secure communication over a computer network. ### User Permissions User permissions are settings that determine what actions a user can perform within a system, controlling access to files, features, or functionalities. ### Cloud Backup Cloud backup is a service that automatically copies data from a device or system to secure, remote cloud storage for safekeeping and easy recovery. ### OAuth OAuth is an open standard for access delegation, commonly used as a way for internet users to grant websites or applications access to their information on other websites but without giving them the passwords. svg]:px-2.5" type="button">View all Built for webflow ### Built for Webflow.
