How do I reset my password

I've looked through previous questions but without a search button I am not finding an answer.

I'm in the website typing this on my phone, I do not have a laptop.  I deleted my Cycle.Travel app and reinstalled it but I now can not get it to accept my saved password.

The password worked for me to access this forum.  

Please advise how I reset my password in the app.  Thanks Amanda in NZ

I've used 2 emails by mistake

Hi, I'm in New Zealand.  I set up cycle travel app on my phone last year under my email then became a supporter in December under our (as a couple) email address.  So I don't think I'm getting any advantages of being a supporter? but I'm not exactly sure.  How do I change so they are under the same address, I don't mind which one.  Thanks Amanda
