Gmail's new Inbox app is pretty awesome, but it's still invite-only. If you have a friend that's using Inbox, you can get access on your own device with their help -- even if they don't have any invites to give out.
The process, courtesy of WonderHowTo, is simple:
- Download Inbox on your phone through its app store, either Android or iOS. You won't be able to sign in with your account, since you don't have access, but download it anyway.
- Have your friend log into their Google Account on your phone. For Android, you'll want to do this under Settings > Accounts. On iOS devices, log in through another Google app, like Gmail or Chrome.
- Open Inbox and, when prompted, choose their account to sign in.
- Go to Inbox's settings and select "Manage Accounts". Flip the switch for your account to "on". You should now have access to Inbox on your account.
- Remove your friend's account from your phone. Again, on Android, do this through Settings > Accounts. On iOS, head back to the "Manage Accounts" screen in a Google app, tap "Edit", and delete your friend's account.
After performing this process, your friend's account will no longer be connected to your phone, but you'll still have access to Inbox. According to WonderHowTo, this only works for one degree of separation. That is, if you never officially got an invite to Inbox, you can't repeat this process with other people -- only the original invitee can.
