Support Self-Service User Attribute Verification Across ThunderID SDKs #6230

Current Limitation

ThunderID SDKs do not currently provide built-in support for authenticated users to verify their own email addresses and mobile numbers through self-service attribute verification flows. Applications must implement this functionality manually.

Suggested Improvement

Introduce self-service attribute verification support across the JavaScript, React, Vue, Next.js, Nuxt, iOS, Android, and Flutter SDKs.

The SDKs should support:

• Initiating and completing self-service attribute verification flows.
• Verifying email addresses and mobile numbers using supported verification methods.
• Displaying attribute verification status in user profiles.
• Allowing users to verify unverified or updated contact attributes.
• Providing reusable components or APIs appropriate to each SDK.
