When you open Reunit Wallet for the first time, you have the option to create a new wallet by clicking on “Create a new wallet”.
------------------------
A series of 12 words will be communicated to you: you should never lose it!
Indeed, this series of words called “seed phrase” will allow you to recover the private key corresponding to your address.
We advise you to store it “cold”, that is to say on paper, and in several copies.
Be careful never to expose it on the internet!
Whoever has these 12 words will be able to take control of the funds available on your keys.
Also choose a password that you will remember: this password, and only this password, can be used to unlock your backup if you make one.
