Open Rights Group has responded to comments by the Home Secretary Amber Rudd MP about the need for the police to be able to access encrypted messages.
Rudd made the comments on the BBC's Andrew Marr programme.
Executive Director Jim Killock said:
"It is right that technology companies should help the police and intelligence agencies with investigations into specific crimes or terrorist activity, where possible. This help should be requested through warrants and the process should be properly regulated and monitored.
"However, compelling companies to put backdoors into encrypted services would make millions of ordinary people less secure online. We all rely on encryption to protect our ability to communicate, shop and bank safely."
