Edge Browser

The Microsoft Edge browser refers to two different browsers: the original release from 2015 (now called "Microsoft Edge Legacy"), and the Chromium-based version from June 2020 that inherited the name "Microsoft Edge".

When adding support for WebAuthn, special considerations must be made for Microsoft Edge Legacy:

• The browser global TextEncoder is not supported. This means @simplewebauthn/browser will not work in this browser without a polyfill for this API. MDN includes a spec-compliant polyfill that can be copied into your project. Various browser polyfill libraries exist on NPM as well.
