Seed phrase
On paper
12 or 24 words. Restores the wallet anywhere.
Passphrase
Only in your head
Optional. The same phrase plus another word is another wallet.
Write it on paper. Do not put it in a photo, a cloud note, or a chat. Do not type it into a website.
The password on the wallet file is separate. The password opens the file on this device. The phrase restores the wallet when the file or the password is gone.
Order matters
The words only work in the order you wrote them. A swapped pair is a different wallet.
It is not the password
The password opens the file on this device. The seed phrase restores the wallet when the file is gone.
Shown once, then hidden
On creation the words can be shown or hidden, and copied. After that screen, Terius does not show them again. The paper copy is the backup.
