Everything You Need to Know About 399days Login

Logging in to 399days is simple and secure. Once registered, you can sign in anytime, from any device, using your username or mobile number. Your account works seamlessly across mobile browser, desktop, and the app.

The login page asks for just two things — your username or registered mobile number, and your password. Enter them correctly and your account opens within seconds. No extra verification or OTP is required every time.

Using multiple devices is no problem at all. 399days supports logging into the same account from multiple devices simultaneously. For your security, though, always remember to end your session after using a public or shared device.

Login Security — Your Information Is Protected

Your login credentials are stored with the highest level of security at 399days. Every login session is protected by SSL encryption, meaning your password and username are never visible to any third party.

Logging in from an unfamiliar device or a new location may trigger additional verification. This protects your account from unauthorized access. Keeping two-factor authentication (2FA) enabled adds an extra layer of security.

Warning: Never share your password with anyone. 399days will never ask for your password by phone, email, or chat.

What to Do If You Forget Your Password

Forgetting your password happens to everyone. On the 399days login page, simply click "Forgot Password?" and a reset code will be sent to your registered mobile number or email.

Use the code to set a new password — the whole process takes just 2 to 3 minutes. Choose a strong password by combining uppercase and lowercase letters, numbers, and special characters to keep your account as secure as possible.

  • Click the "Forgot Password?" link on the login page.
  • Enter your registered mobile number or email address.
  • Use the OTP or reset link you received.
  • Set a new strong password.
  • Log back in with your new password.

Benefits of Accessing via the Mobile App

Download the 399days mobile app and log in on Android or iOS for added convenience. Once you're logged in on the app, you won't need to enter your password again — just use fingerprint or face unlock for instant access.

Get push notifications on the mobile app — you'll be alerted instantly for new bonuses, game updates, and completed transactions. The app loads faster than a browser and delivers a smoother gaming experience on mobile.

What to Do If You Have Trouble Logging In

Login issues can happen — a wrong password, a temporary account lock, or a connection problem. When that occurs, try the steps below:

  • Make sure your password is correct — check that Caps Lock is turned off.
  • Try clearing your browser cache and cookies, then attempt again.
  • Try using a different browser or device.
  • Reset your password using the "Forgot Password?" option.
  • If the issue persists, contact our 24/7 live chat support.

Entering the wrong password 5 times in a row may temporarily lock your account. Wait a moment or contact support — you'll get it sorted quickly.
