Controls the access rights of individual apps to protect data.
Device Encryption
Ensures data is unreadable without the correct key, even if the device is physically accessed.
Walls (Data & Applications)
Your personal data (contacts, photos, messages) and installed applications are stored within the secure walls of the device. External Threats:* Phishing Attacks: Attempts to steal credentials through deceptive tactics.
Malware
Malicious software designed to steal data or control the device.
SIM Swapping
Attackers taking over your phone number.
Physical Theft/Loss
Risk of unauthorized access to your device. How Number Verification Works in the Fortress:
1. Authentication Request
When you attempt to access a protected feature (e.g., account recovery, password reset), the system initiates an authentication request.
2. Number Verification Trigger
The system prompts for number verification. A code is sent to your registered phone number.
3. Code Entry
You enter the verification code received on your phone.
4. Authorization
If the code is correct, the system grants access, completing the authentication process. If the code is incorrect, access is denied.This architecture ensures that even if one security layer is breached, others remain in place to protect your data. Number verification serves as a critical checkpoint, safeguarding your digital assets and preserving your privacy.
