Hey there, let's break down your problems and answers clearly!

一、IE浏览器下登录谷歌账号的可行方案 #

Since your school computer only has Internet Explorer (which doesn't support Google's security key verification flow), here are practical workarounds:

• Try a Chromium-based browser (if permitted)：Microsoft Edge is built on Chromium now and fully supports WebAuthn (the protocol powering Yubico security keys). Check if your school IT allows installing Edge—many institutions approve it as a Microsoft product. If you can't install it, look for a portable Edge version that runs from a USB drive (no admin rights needed in most cases).
• Use backup 2FA methods：If you can log into your Google Account from another device, go to your security settings and confirm you've set up alternative verification options like SMS codes, Google Authenticator, or printed backup codes. You can use these to bypass the security key requirement when logging in via IE.
• Contact your school IT team：Explain your situation—they might be able to install a supported browser temporarily, or adjust settings to help you use the security key through an approved channel.
• A note on IE limitations: Internet Explorer has almost no support for WebAuthn, the standard that enables secure key logins. Google can't support this feature on IE because the browser's outdated architecture can't handle the encrypted, secure communication required for the key to work properly.

二、谷歌要求Chrome的原因，以及Word中密钥输出文本的解释 #

• Why Chrome?：Google uses the WebAuthn protocol for security key authentication. WebAuthn is a modern web standard fully supported by Chrome, Edge, Firefox, and Safari—but not by Internet Explorer. IE's old codebase can't implement the secure device-to-browser handshake WebAuthn needs, so Google restricts this feature to browsers that support the protocol.
• Text output in Word: When you use your Yubico key outside a browser (like in Word), it defaults to its legacy one-time password (OTP) mode. In this mode, the key acts like a keyboard and types a pre-configured string of text. WebAuthn only works in browser environments that recognize the protocol—since Word doesn't support WebAuthn, the key falls back to this basic OTP behavior.
