Set default value for password

How can I set a default value for the Core CB field 'password'?

The password field is not displayed at Registration so no default value can be specified in Field Management Edit.

I use a CB Auto Action with triggers onAfterNewUser and onAfterUserRegistration to:

1. generate a membership number (which works fine)
2. generate a username based on input values (which works fine)

The third action in this Auto Action is to set the value of the Core CB field 'password' - but this doesn't work.

The thought has occurred to me that maybe it is working but I should be using the encrypted equivalent instead?

You can't, that doesn't even make sense to have a single default value for password field. If it's not available for a user to supply a password then one will be generated. The password field on store will encrypt so if you do change it then no you don't need to encrypt it as it'll do so on store.

There could be any number of reasons why the password didn't store from CB Auto Actions. Most commonly it's due to a store that fired after the action. If you are chaining multiple field actions together be sure to tell your action to reload the user object under parameters or do it all in 1 action.
