Europol's chief, Catherine De Bolle, stated that technology giants have a "social responsibility" to give the police access to encrypted messages used by criminals.
Experts argue that creating a backdoor for law enforcement will undermine the protection of all users and have unintended consequences.
Backdoors in encrypted systems make them vulnerable to exploitation by criminals and can lead to mass surveillance.
The debate on encryption continues, with tech experts supporting the need for end-to-end encryption, while law enforcement argues for backdoors.
