Setting a Default Passcode
Setting a default passcode is very similar to setting a regular passcode.
(If you don't know how to set an email passcode, learn how to do it here: https://support.safebolt.com/article/95-setting-a-passcode)
Begin by composing an email as you would any other; click "New Message," and enter your recipient, subject, and message.
Then, click on the "Encrypt" button in the top left of your message window.
In the pop-up window, enter your desired passcode, and directly underneath, check the box that says "Set as default passcode for this recipient." This passcode will then autofill for every email you send to this recipient.
Click "OK" at the bottom of the pop-up window to save your default passcode.
