About Local MFA — Offline Authenticator
Local MFA is a privacy-focused offline authenticator for securely storing and generating TOTP two-factor authentication codes directly in your browser.
Your authenticator data is kept in an encrypted local vault protected by your master password. Local MFA is designed to work without requiring an online account or cloud synchronization.
KEY FEATURES
• Offline TOTP authenticator
Generate time-based one-time passwords (TOTP) directly on your device.
• Encrypted local vault
Authenticator secrets are stored locally in encrypted form.
• Master password protection
Protect access to your authenticator vault with a master password.
• QR code import
Quickly add compatible authenticator accounts by importing QR codes.
• Manual account setup
Add TOTP accounts manually when a QR code is not available.
• Encrypted backups
Create encrypted backups of your authenticator vault so you can securely restore your accounts when needed.
• Simple account management
Add, edit, organize and remove authenticator entries from a clean and straightforward interface.
• No mandatory account
Local MFA does not require you to create an online account in order to use the authenticator.
PRIVACY-FOCUSED DESIGN
Authentication secrets are sensitive information. Local MFA is designed around local storage and encryption so users remain in control of their authenticator data.
The extension does not require cloud synchronization for its core authentication functionality.
WHO IS LOCAL MFA FOR?
Local MFA is useful for anyone who wants a convenient browser-based TOTP authenticator for services that support two-factor authentication, including developer tools, email services, hosting platforms, dashboards and other online accounts.
IMPORTANT
Local MFA generates TOTP codes for services that support standard time-based one-time passwords. Availability and compatibility depend on the service where two-factor authentication is being configured.
Keep your master password and encrypted backups secure. Losing access to the information required to unlock an encrypted vault or backup may prevent recovery of the stored authenticator data.
