When you upload a file to Thunderbird Send, you will be asked if you want to create a password to protect it.
Thunderbird Send encrypts your files end-to-end, so only the people you share them with can open them. However, including a password adds another layer of safety! That way, if a third party gains access to the link (or even your email accounts), they still won’t be able to open it.
Adding a Password to Your File
- After uploading your file, you will be asked if you want to create a file password.
- Check the box marked “Protect this file with a password.”
- In the field marked “File Password,” enter in the password you want to set.
- Click the icon that looks like an eye to double-check what you have typed.
- Press the “Next” button to save the password and continue.
When you have set up your file and send the link to your recipient, share the password with them through another platform (such as a text or over an app’s instant message).
It is very important that you share the file link and password over different channels to make sure that a third party can’t gain access to both at the same time.
Enjoy the security and peace of mind that Thunderbird Send provides!
