1. Install Briar
Download it from F-Droid or Google Play (Android only). Creating an account only requires a username and a password, no phone number or email. All content is encrypted locally on your device.
2. Create an account
On first launch, set up an account with a nickname and a secure password (minimum 8 characters).
3. Add contacts
Tap the "+" icon on the contact list to access two options: add remote or nearby contacts.
4. Add remote contacts
Share your briar:// link with the contact. Paste their link into the text field and click "Continue". Briar will keep trying to connect regularly until it succeeds.
5. Add nearby contacts
Meet in person and scan each other's QR codes. The devices exchange information within seconds and add the contact automatically.
6. Messaging
Tap a contact's name to send them private messages. All messages in Briar are end-to-end encrypted.
7. Private groups
Go to the main menu, select "Private groups" and create a new one by naming it, selecting contacts and sending invitations.
8. Connection settings
Go to Settings to set the connection modes: Tor (with or without bridges), Wi-Fi restriction, mobile data control, and connect only while charging.
9. Screen lock
Turn on screen lock in the Security section to protect your privacy. It uses your device's existing PIN, pattern or password. Once enabled, a "Lock app" option appears in the main menu.
