Best Practices for Secure Communications Use Encrypted Platforms Use Signal for sensitive discussions. It offers end-to-end encryption, minimal metadata retention, and open-source transparency . Turn on disappearing messages, registration lock, and screen lock. Secure Accounts and Devices Use strong, unique passwords and enable two-factor authentication (2FA) or passkeys on all communication apps. Store passwords in a manager such as 1Password or Bitwarden. Keep apps and operating systems updated to close security vulnerabilities. Use long log-in passwords on your devices and disable message previews on lock screens. Protect Shared Files and Metadata Before sharing, strip metadata from Word and PDF files using the Document Inspector in Word or Remove Hidden Information in Adobe Acrobat . For highly sensitive material, share sanitized versions via encrypted services such as Tresorit, which provides end-to-end encryption. Establish Organizational Communication Protocols Designate which platforms are approved for which types of communication (e.g., Signal for private, email or Slack for non-sensitive). Use separate channels for internal and external communication. Label sensitive topics and documents clearly. Include secure-comms guidance in your incident response plan (who to contact, when to switch to encrypted tools). Minimize Data Exposure Collect and share only essential personal information. Avoid over-collection in communication platforms and forms. Train staff on privacy principles and proper use of encrypted tools. Maintain Privacy in Collaboration and AI Tools Avoid uploading personal or confidential data to generative AI systems; use placeholder text in drafts. Keep advocacy or campaign plans off open systems unless sanitized.
