Hey guys! I want to know if is possible to set 6 digits (I mean just numbers) as a password

Yes I think that should not be a problem. You have a lot of control over the password policy. Check the password policy doc for some best practices.

Where can I do this when using hosted Ory?

Hello @full-midnight-13013, apologies I was out of office for some time. You can configure this in the identity service configuration. See here : https://www.ory.sh/docs/guides/cli/identity-cli#export-configuration-from-the-ory-network Let me know if you have more questions
