Instead of using a QR code as a security key, there are other methods that can be used for authentication and security, such as physical security keys, biometric authentication, or one-time passcodes sent via SMS or email. These alternative methods can provide additional layers of security and make it more difficult for unauthorized access to occur. It's important to consider the specific security needs and use cases when choosing the most appropriate method for authentication and access control. **
