We take securing your credentials extremely seriously. Here's how we manage your Exchange calendar credentials:
When you connect your Exchange calendar to Calendly by providing your login credentials, we pass your email and password to our servers through an encrypted SSL connection. Once your credentials reach our servers, we encrypt it before storing them in our database.
The encryption key is stored as an environment variable on our servers, ensuring more security. When we need to access your Exchange calendar, we decrypt your credentials in memory, and access your calendar with the credentials.
We never store your decrypted credentials anywhere.
All of this ensures that your Exchange calendar credentials are very safely stored using industry best practices.
