Step by step
Open the options
Before creating the link, open the transfer options and pick the Protection tab.
Set a password
Type a password, and turn on enhanced encryption for a second layer of protection.
Share separately
Send the link one way and the password another way, for example by email and by text message.
How the password is checked
The password never travels over the network. Each browser transforms it slowly and irreversibly (with PBKDF2), then the two browsers check that they get the same result. With enhanced encryption turned on, the password is also part of the encryption key, so without it the data is unreadable.
After 5 wrong attempts, the transfer locks and the sender has to create a new one.
Choosing a good password
Use a few unrelated words or a long phrase rather than a short word with symbols. It only needs to be good enough for the time the link is open, and easy for your recipient to type.
