Olvid is a French encrypted messenger app that is free and open-source. It does not store or collect any person-related data, like phone numbers.[1]

In 2021, the ANSSI, the French government's information security authority, said that the app passed its First-Level Security Certification (CSPN, fr:Certification de sécurité de premier niveau), something that no messaging app has received before.[1]

Security[edit]

Olvid's website states that it is the first messenger with a guarantee that a compromised server does not impact the security of any message. The users are authenticated, but yet remain anonymous to Olvid.[2] Though all messages transit a server, message data and metadata are encrypted on the sender's phone and only decrypted on the receiver's phone. The only data not to be encrypted is the receiver's public key, as it is required to send the message to the correct destination. The server receives the sender's IP address, but Olvid still works with any VPN service or the Tor network.[3]

Adoption[edit]

RAID, a special unit of the Police Nationale selected Olvid for its secure internal communications in 2021.[4]

In November 2023, a circular issued by the French Prime Minister called government members and government officers to replace WhatsApp, Telegram and similar messengers by Olvid.[5]
