Purpose

This pull request adds support for passkey-based authentication and registration to the sign-in and sign-up flows. It introduces new state management and effect hooks to trigger browser passkey popups and handle their responses, and updates the internationalization (i18n) files with passkey-related strings in multiple languages.

Passkey Authentication & Registration Integration:

• Added state management and effect hooks to SignIn.tsx and BaseSignUp.tsx to detect passkey challenges or creation options from the backend, trigger the browser's passkey UI, and submit the results to complete the authentication or registration flow. [1] [2] [3] [4] [5] [6] [7] [8]

Internationalization (i18n) Updates:

• Extended the I18nTranslations interface and updated translation files (en-US, fr-FR, hi-IN, ja-JP, pt-BR, pt-PT, si-LK, ta-IN, te-IN) to include new passkey-related UI strings for button labels, headings, and descriptions. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

Utilities:

• Imported new utility functions handlePasskeyAuthentication and handlePasskeyRegistration to handle the browser interactions for passkey flows. [1] [2]

These changes enable seamless passkey-based authentication and registration across supported languages, improving both security and user experience.
