2FA二维码生成器
为Google Authenticator、Authy、1Password及其他2FA应用生成TOTP二维码。
如何使用本工具
- 1
Type the service name into the first field (this becomes the issuer label, e.g. RevealTheme).
- 2
Enter the account identifier, usually the user's email or username.
- 3
Paste an existing Base32 secret, or click Random to generate a fresh 32-character one with crypto.getRandomValues.
- 4
Scan the QR code that appears below with your authenticator app, or copy the otpauth:// URI shown under it.
什么是2FA二维码生成器？
两步验证应用会扫描以二维码形式编码的otpauth://URI，以配置基于时间的一次性密码（TOTP，RFC 6238）。本工具根据服务名称、账户标识符和Base32密钥构建该URI，然后将其渲染为可扫描的二维码。
常见使用场景
Demoing a 2FA enrollment flow in a tutorial, slide deck, or product screenshot without wiring up a real backend.
Generating a test TOTP secret while developing or QA-testing a login system that uses standard SHA1/6-digit/30-second codes.
Re-encoding a Base32 secret you already hold (for example from a recovery backup) into a fresh scannable QR.
Teaching teammates how the otpauth:// Key URI Format is structured by showing the URI printed beneath the QR.
Quickly checking whether an authenticator app accepts the default TOTP parameters before committing to a server-side library.
Creating a throwaway 2FA setup for a sandbox or staging account where the secret does not protect anything sensitive.
