Tips for Keeping Your Account Secure
Build a few simple habits to keep your login safe. bd big always uses SSL-encrypted connections, but some caution on your end is also needed.
Use a strong password
Choose a password of at least 8 characters — a mix of uppercase letters, lowercase letters, numbers, and special characters. Avoid dates of birth or simple numbers.
Never share your OTP with anyone
bd big will never ask for your OTP code by phone or message. If anyone asks for this code, be suspicious immediately and report it via live chat.
Watch out for fake sites
Fake websites that look like bd big do exist. Always check that the URL in your browser's address bar is correct before logging in.
Be careful on public devices
If you log in at a cyber cafe or on someone else's phone, always log out when you are done and do not use the "Remember me" option.
Change your password regularly
Change your password once every three to six months. Do not use the same password on more than one site.
Keep your mobile number up to date
If your registered mobile number changes, update it in your account right away. OTPs will be sent to that number.
