DAV Setup Guide

Synchronize your calendars and contacts across all devices with our unique privacy-preserving DAV technology

🔧 General Connection Information

We offer a truly unique privacy-preserving WebDAV/CalDAV/CardDAV system of our own design and build.

It uses a random username and random password for authentication (our own dual-random authentication), which gives you complete privacy in authentication. The server also uses random URLs, giving you complete resource access privacy. It provides hyper-granular permissions per auth pair and you can create as many as you need with full or limited permissions. Permissions, including expiration, can all be changed without generating a new auth pair.

No other DAV server anywhere offers these features! This is our own design, from the dual-random auth, to the privacy-preserving urls, to the dynamic hyper-granular permissions!

Use the generated credentials to configure any CalDAV/CardDAV client:

Username: The randomly generated username (e.g. XF45F@codamail.com)

Password: The associated random password (not your account password)

Server URL: https://codamail.com/dav/

Important: You MUST click the Calendar icon in webmail first so it will create the default calendar. Both the username and password are shown only once. They operate as a pair, which means a different password cannot be used with the same random login. You must use them as a pair. Use the copy button to save each credential while they are visible. Neither are stored and neither can be recovered if lost. If you lose either you must delete the auth pair and create a new one.

💡 Troubleshooting Tips

💡 Don't see any Calendars when creating auth pair? Ensure you clicked the Calendar icon in webmail at least once first, this creates your default calendar

💡 Authentication failed? Make sure you're using the random username and associated random password, not your email username or password

💡 Can't find calendars? Try the full URL: https://codamail.com/dav/

💡 Lost your credentials? Generate a new token from your account settings

💡 Sync issues? Check that your client supports modern CalDAV/CardDAV standards

💡 Connection problems? Verify your internet connection and firewall settings
