Do you mean you want to limit which fields will be visible to users
when they register and edit their profile?

You need to use a custom auth_user table and set writable=False for
those fields they cannot edit, and readable=False for those that
should not be visible. For example:

db.define_table('auth_user',
                Field('first_name', length=512,default=''),
                Field('last_name', length=512,default=''),
                Field('username',length=32,default='',
 
requires=(IS_NOT_EMPTY(),IS_NOT_IN_DB(db,'auth_user.username'))),
                Field('email', length=512,default='',
 
requires=(IS_EMAIL(),IS_NOT_IN_DB(db,'auth_user.email'))),
                Field('password', 'password', readable=False,
label='Password',
                      requires=[CRYPT(auth.settings.hmac_key)]),
 
Field('is_admin','boolean',default=True,readable=False,writable=False),
                Field('registration_key', length=512,writable=False,
                      readable=False,default=''),
                Field('reset_password_key', length=512,writable=False,
                      readable=False, default='',
                      label=auth.messages.label_reset_password_key),
                )


As you can see is_admin is not readable and writable.
auth.define_tables()                           # creates all needed
tables
