If you ever leaked your key you should make sure to change your keys afterwards. If unsure - you can change them again.
However, please keep in mind, that as important as not leaking your keys is to not lose them. Make sure you saved your new keys in a safe place because nobody would be able to help you to recover them when lost.

thanks - i was not sure if that left me exposed - am very careful with storing them in a few places. Good to connect with you, all the best, David
