Password validation Xano/Adalo

Hi there,
What is the best way of applying password validation to inputs to ensure only passwords that meet the minimum criteria on sign-up (e.g. 8 characters long, 1 numeric, 1 character) before they are sent to Xano?

Note: I am using Adalo as my front-end and Xano as my back.
Here is the problem shown on loom. Any help much appreciated!
