"A dangerous approach" – Experts urge the Swedish Parliament to reject the encryption backdoor law
Sweden is considering enforcing new obligations for Signal, emails, and similar services to share users' data with law enforcement. Experts warn what can go wrong.

- More than 200 experts urge Sweden to reject a bill that would mandate encryption backdoors
- If passed, the legislation could come into force as early as March 2026
- The Swedish Army also warns that a backdoor would create vulnerabilities that third parties could exploit
Over 200 experts have called on the Swedish Parliament to reject a proposed law that would force the likes of Signal, WhatsApp, and email service providers to create an encryption backdoor in their software.
The draft bill seeks to introduce new obligations on data retention and access to electronic information for law enforcement while "ensuring respect for fundamental rights and freedoms."
Yet, the coalition, made up of some of the best VPN and secure email service providers, cryptographers, and digital rights advocates, warns that the new rules "would greatly undermine the security and privacy of Swedish citizens" instead.
The security risk of weakening encryption
As experts pointed out in a joint open letter published on April 8, 2025, "the legislation presents a dangerous approach which would instead create vulnerabilities that criminals and other malicious actors could readily exploit."
Encryption refers to the scrambling of data, making it unreadable and preventing third-party access. Specifically, end-to-end encryption (E2E) is the technical infrastructure that encrypted messaging apps use to keep your messages private between you and the receiver, end to end.
The proposed Swedish legislation seeks to make it easier for law enforcement to fight crime by forcing companies to store and provide access to people's private communication upon request.
However, experts have long argued that this isn't possible without creating a backdoor that fundamentally breaks the security infrastructure upon which encryption is built.
It's like building "a master key that unlocks every door in a building," noted the coalition, adding that "compromising encryption would leave Sweden’s citizens and institutions less safe than before."
Sweden wants to #backdoor #encryption. But we, together with 230+ orgs, are saying no.#NoToBackdoors
