Progressive Web Apps (PWAs) can be designed and implemented with security in mind, but their security depends on various factors, including the specific implementation and practices followed during development. Here are some key points regarding the security of PWAs:
Use HTTPS for secure communication.
Implement strong authentication methods.
Employ Content Security Policy (CSP) to mitigate code injection risks.
Securely store sensitive data.
Benefit from automatic updates for quick patching.
Conduct regular security assessments and follow best practices.
