4 session security features
IP Match Check
If an unknown IP appears, extra verification may be requested; this helps access control outside Dhaka.
Device fingerprint
It recognizes the same phone later more quickly by matching the phone type, browser, and settings.
Session Timeout
If left idle long, the session ends, preventing entry on a blank screen for anyone.
What happens if suspicious activity occurs
If someone signs in from another device, a warning may appear; the system ends the previous session and requests new verification.
This may be annoying, but for security it's necessary; if unauthorized people gain access to the account, recovery later is very difficult.
Act quickly in such case
- 39BD Sign In again from your phone
- Change password if suspicious
- Enable two-step verification
