# Where is the Public Key
When you are setting up a vault, you need to enter the address and public key information of the other signatories.
There are **two methods** to obtain someone's public key:
## Method 1
Upon entering the signatory's address while setting up the vault, click the forward button. The recipient of the link can then open it, connect their wallet, and the public key will be automatically populated.
Initiator
Signatory
## Method 2
By using Unisat to connect to Bitune, click on the address in the upper right corner, then click the key icon to obtain your public key.
