2FA Code Generator

The 2FA Code Generator allows users to input their TOTP secret keys to generate one-time codes directly in their browser. It does not require an API or storage of secrets, ensuring that everything remains local to the user's session. This tool is suitable for anyone needing to generate 2FA codes often without the risk of exposing their secrets to external servers.

2FA Code Generator creates time-based one-time passwords (TOTP) directly in the user's browser. It allows users to paste up to 50 2FA secret keys and generate corresponding codes. No sensitive information is stored, making it a safe temporary solution for generating codes needed for two-factor authentication. Users paste their 2FA secret keys into the generator, which calculates the TOTP codes using browser-based cryptography. Generated codes refresh automatically, and users can easily copy or clear them as needed. The generator operates fully within the browser, requiring no server interaction for code generation. This tool is designed for anyone needing to generate TOTP codes securely and privately. It caters to users who prioritize safety by ensuring secrets remain in-browser and not stored externally, making it especially suitable for temporary use during account authentications.
