Your Vault is a self-custody wallet. This means that only you have the password and backup key for it. Nuri can neither see nor restore them. This gives you the highest level of security, as nobody but you have access to your Vaults and the cryptocurrency on them.
Your password for the Vault is very likely not the same as your bank account, as we recommend that you do not reuse it when creating it.
Your Vault will not be blocked even if you enter incorrect passwords several times. So you can safely try out different passwords that you might have used.
You can restore the funds in your Vault externally if you still have access to your main and backup keys. Find the full instructions on how you can recover your Bitcoin Vault.
