Common Mistakes to Avoid
1. Not Verifying Contacts
Reason: Failing to verify the security code with your contacts leaves your communication vulnerable to man-in-the-middle attacks.
Solution: Always manually verify the security code displayed on your screen with your contact's code to ensure secure communication.
2. Using Signal on Unsecured Devices
Reason: Using Signal on a jailbroken or rooted device compromises the app's security features and makes your messages vulnerable.
Solution: Ensure your device's operating system is up-to-date and that it hasn't been jailbroken or rooted.
3. Ignoring App Updates
Reason: Outdated Signal apps may contain security vulnerabilities that hackers can exploit.
Solution: Enable automatic updates or regularly check for and install the latest version of the Signal app.
