Is there a bluetooth module for Arduino that can have the password disabled?

Question

Arduino

Good day to all!
I am developing a project on arduino with bt module. In my project, it is necessary to make sure that the android automatically connects to the bt module, but I ran into such a problem: when connecting, a pin code is required.
I have already learned that you cannot programmatically insert it automatically. Then there is only one way out, to find the module without a password.
I looked at hc-05(08), hm-10(11) and didn't find passwordless pairing functions in them. If you know how to bypass password entry or know a good module that can be powered by 2.7V and does not require a password, please write.
