You try to sign in.
The password is correct.
But access is denied.
A warning appears.
“Multiple login activity detected.”
Your account is now restricted.
Why This Happens
- Logging in from multiple devices at the same time
- Switching between mobile and desktop rapidly
- Using public Wi-Fi or shared networks
- Browser sessions staying active in the background
Security systems flag overlapping sessions as suspicious.
What Triggers the Block
- Simultaneous logins from different locations
- Frequent device switching in a short time
- Account sharing detection
- Session conflicts across apps and browsers
The system assumes unauthorized access.
How to Restore Access
- Log out from all devices
- Reset your password
- Verify identity via email or SMS
- Wait for automatic session reset
Most multiple-login restrictions are temporary.
Access usually returns after verification.
