Trump allies and critics turn to Signal for secure communication

Signal’s rise in popularity underscores the growing demand for digital privacy, with government officials, corporate leaders, and political activists relying on it as a key tool for secure communication

In a remarkable convergence of interests, text-and-voice app, Signal, has become an essential communication tool for both government officials and activists, valued for its strong privacy protections. The messaging platform, known for its end-to-end encryption, ensures that only the sender and recipient can read messages, making it particularly popular among those who need secure communication.

Data from analytics firm Sensor Tower shows that Signal’s popularity is growing. In the first quarter of 2025, downloads in the US increased by 16% compared to the previous quarter, and by 25% compared to the same period in 2024. This rise in usage reflects the growing demand for secure messaging apps, especially among government officials. A report by the Associated Press revealed that over 1,100 government employees across all 50 states now use Signal, with the app becoming a common tool in Washington, DC. Aides and political appointees often turn to Signal for confidential conversations.

Signal’s use extends beyond government circles. Elon Musk’s team, which is working to reduce the size of the federal bureaucracy through the Department of Government Efficiency, has reportedly adopted Signal for secure communication. Musk himself used the app during his 2022 purchase of Twitter and continues to rely on it for private discussions. This trend shows that high-profile business and political figures also prefer the app for its privacy features.

The app has also gained recognition from governments around the world. In 2020, the European Commission advised its staff to use Signal for secure messaging. In the US, the Cybersecurity and Infrastructure Security Agency (CISA) recommended that senior government officials switch to encrypted communication apps like Signal. The US Senate has long authorized the use of Signal for legislative staffers, emphasizing its role in secure government communications.

Signal's role in privacy and security

Despite its positive reception in secure communication, Signal’s privacy features have raised concerns among law enforcement. Criminal organizations, including drug dealers, frequently use the app to evade detection. A 2022 report from the Drug Enforcement Agency (DEA) highlighted the app’s use by criminals. Signal was also used by rioters to coordinate the January 6, 2021, Capitol attack, as revealed in court filings.

The app is also crucial for political resistance. Whistleblowers within the government, especially those opposing former President Donald Trump’s efforts to downsize the federal bureaucracy, have turned to Signal to avoid surveillance. Protesters, including those opposing Trump, also use the app to organize and communicate securely.

Signal’s rise in popularity highlights a growing concern over digital privacy. Whether used by government officials, corporate leaders, or political activists, the app is increasingly seen as a necessary tool for secure, private communication in today’s world.
