Should i delete pairing info after key change?

[Gattuso77]

I am using nrf51822, sdk 12.3.0, softdevice 2.0.1 , i am wondering what is the best practice after user changes the pairing key , should i delete pairing info on the NRF in background automaticaly to prevent previously paired devices to connect without knowing new key or should i maybe expose function and leave it to the user (App Developer) to manualy delete pairing info if he wants to?

It depends a bit on the application, if only one device should be bonded at the time I would delete the old bond. If multiple devices can be bonded, then maybe the app should have some way of handling that.
