I am running Lollipop and want to change my gmail password. How do I do that?
Go to this page in your webbrowser: https://myaccount.google.com/security/signinoptions/password
1. Goto your @EMAIL for Android (not the one for gmail and not in your account settings).
2. Select the email account then hit your menu tab goto -> more, goto -> account settings -> goto incoming -> change your new password here.
Hope this helps.
Edit : If this doesn't work, change your password in outcomming too.
