Account Security & Password Management

Keeping your account secure when logging in to 399b is essential. Use a strong password that includes uppercase letters, lowercase letters, numbers, and special characters. Avoid easily guessable passwords such as your date of birth or "123456".

It's a good habit to change your password every 3–6 months to keep your account secure long-term. To update it, log in, go to Account Settings, and select the "Change Password" option.

Enabling two-factor authentication (2FA) adds an extra layer of security to your account. Once active, every time you log in from a new device or browser, a verification code will be sent to your mobile — you'll need to enter it to confirm your identity. This means even if someone gets hold of your password, they still won't be able to access your account.

Common Login Issues & How to Fix Them

There are a few common issues that can come up when logging in to 399b. Most of them are easy to fix. Here are the most frequent problems and their quick solutions:

• Wrong password: Check whether Caps Lock is on. Also make sure you're not typing your password with a Bangla keyboard layout — switch to English if needed.
