⚠️ Deprecated ⚠️ U2F second factor provider for Nextcloud

⚠️ The U2F standard has been deprecated and therefore this app will be discontinued. The Two-Factor WebAuthn app can be used as a replacement. Here you can find migration instructions.

Requirements

In order to use this app for authentication, you have to use a browser that supports the U2F standard:

• Brave Browser
• Chromium
• Google Chrome
• Microsoft Edge
• Mozilla Firefox
• Opera

Login with external apps

Once you enable U2F with Two Factor U2F, your applications (for example your GNOME app) will need to login using device passwords. Which can be managed in your security settings.

Official aplications such as the Android or IOS clients and desktop clients can use much safer tokens to login. Apps will automatically redirect you to a browser window to login as usual.

Development Setup

This app uses composer and npm to manage dependencies. Use

composer install
npm install
npm run build

or if you're using Krankerl

krankerl up

to set up a development version of this app.
