Email sign-in is now OTP-first, with magic link fallback
Cryptbin now prioritizes one-time passcode (OTP) for email sign-in and keeps magic links as a fallback path.
Email authentication now defaults to OTP so users can complete sign-in with a short code directly in the app.
When OTP is unavailable or blocked in a specific flow, magic link remains available as a fallback to preserve reliability.
This update improves sign-in clarity while keeping account access resilient across clients and email delivery patterns.
