Recover account on a network without email

What you can do is check in your database for the token relative to the recovery.
https://<your_domain>/setup/recover/<user_id>/<authentication_token.token>

for example:
https://www.passbolt.test/setup/recover/89f69388-50a0-4a6e-ab28-07c374b1fa12/2747ecdf-885e-46ae-83aa-4d2b17c40013

You can get the information in the database:

select token from authentication_tokens where user_id = (select id from users where username = 'your@email.com') and type = 'recover' order by created DESC;
