Open Ninewin and choose Register or Login in the app. Complete ID and email verification first — deposits and withdrawals are blocked until verification finishes.

• Create a unique, passphrase-style password and save it in a reputable password manager.
• Enable two-factor authentication where offered and confirm your device before large bets.
• Start with a small deposit to test deposits and the cashier’s withdrawal processing time.
• Check the app’s responsible-gambling tools (limits, cooling-off) and set them before playing.
• Watch for phishing: never follow login links from unsolicited messages and confirm the site URL before entering credentials.

Takeaway: verify, secure, test a small transaction, and use limits — repeat this checklist each session to keep your account accessible and safe.
