Frequently asked questions
OTP code or verification link?
Use a 6-digit OTP code for mobile apps where users are already in-app. Use a verification link for web signup flows where users check email in a browser.
How long should verification codes last?
10-15 minutes for email verification codes. Shorter expiry (5 min) for sensitive operations. Always show the remaining time in the email.
How do I prevent verification emails from going to spam?
Authenticate your domain (SPF, DKIM, DMARC), use a clear subject line like "Verify your email for [AppName]", and avoid image-heavy layouts.
Should I send a re-verification email?
Yes, if the code expires. Show a "Resend code" button in your app and throttle to prevent abuse. Include the new code in a fresh email, never reuse expired tokens.
Can I customize the branding?
All visual elements are controlled through TypeScript props. Swap logos, colors, copy, and support links without touching the template structure.
