Iran blocks encrypted messaging app Signal

Signal has experienced an increase in downloads in the region following competitor WhatsApp's user requirements update. Internet is heavily restricted in Iran.

Iranians are unable to access the encrypted messaging service Signal.

On Monday, Signal said that Iranian authorities blocked the use of the app in the country.

“Unable to stop registration, the IR censors are now dropping all Signal traffic,” said Signal in a statement on Twitter.

Signal is a mobile messaging application that offers end-to-end encryption. It is commonly used by journalists, activists and others in the Middle East who do not want their communications monitored by a state.

Signal has seen an increase in downloads since the highly popular encrypted messaging app WhatsApp updated its usage requirements. The pending change will result in WhatsApp sharing more data with its owner, Facebook. This prompted people in the region to switch to its competitors like Signal and Telegram as well. Telegram, which has some typical social media capabilities such as subscriptions to channels, is also popular in Iran.

In its statement, Signal said that the blockage happened after an increase in Iranians registering for the app. Signal has vowed to try and enable Iranians to use the app again.

“Iranian people deserve privacy. We haven't given up,” said the company.

The Iranian government regularly restricts internet access to its population. Iranians cannot access Twitter, for example. In October, the Islamic Republic cut internet access entirely amid anti-government protests.
