Several reasons can prevent successful login:
- Caps Lock enabled: Passwords are case-sensitive. Check your keyboard.
- Incorrect email: Ensure you're using the exact email address registered with your account.
- Browser autofill error: Try typing your password manually rather than using saved credentials.
- Recent password change: If you recently changed your password on another device, use the new one.
- Account locked: Multiple failed attempts trigger temporary lockout for security. Wait 30 minutes or use password recovery.
If none of these apply, initiate password recovery through the "Forgot password?" link.
