IOS – Reset Forgotten Restrictions Passcode (Updated For 2017)

Erasing the phone in iTunes will remove the restrictions along with everything else.

Per my comment, you can change the passcode for restrictions under Settings > General > Restrictions

By clicking [enable restrictions] it will prompt you for password, you may disable it and then re-enter the passcode.

You can use a combination of IFTTT and Zapier.

Bizarrely IFTTT supports iOS reminders but not Google Tasks (https://ifttt.com/ios_reminders).

Zapier supports google tasks but NOT iOS reminders (https://zapier.com/app/explore)

The trick is to trigger from IFTTT and send an email to Zapier which triggers on the email and then updates Google Tasks. I've tested it and it works. The biggest challenge is when you have multiple reminders lists. In this case I have not found a good way to dynamically select the google task list from Zapier as it keys off of task list id and not task list name. I suggest making a separate Zap for each reminder list.

Finally this doesn't solve the problem of doing the initial sync. You can use the gtasks app for this.
