Note: When using the same computer/browser for future zkBob sessions, you can access your account with just your password (assuming local storage has not been cleared). If you change browsers/computers or clear local storage, re-enter your secret phrase (or connect your web3 wallet if you used that method) and create a new password to restore the account.
