Let's say my password field has the following validations (not limited to) on my Sign Up form,
- Password length should be 6-12 characters.
- Password must contain at least 1 number.
- Password must contain at least 1 symbol.
And on the application, whenever the focus is on the password field, a tooltip will inform the user of these conditions.
If one of these conditions are not satisfied, it makes sense to display what they did wrong in the message.
Ex: If the password contains a number and a symbol but is not between 6-12 characters, it should display the message:
The password should be between 6-12 characters.
But what if all 3 or 2 conditions are not satisfied. Should I display all 3 messages or is it ok to just say "Invalid password" whatever the case might be since the conditions are shown on the tooltip when the focus is set to the password field.
Will the user feel lost or will they recall tapping the password field again to read the rules?
This is a mobile app. So space is a concern.
