Yes, members can change their password in the app.
Members can visit https://app.yocgolf.org/login/member/assistance and click "Forgot Password" to request the password reset code. The code will be sent to the email on file associated with the member's username being entered.
We recommend checking your spam folder if you are not seeing the code.
Not all active members have app accounts set up. If the "Forgot Password" button isn't working for you, it is likely that you need to create a new app account, which is possible by hitting the "create" button and entering your member details.
