Welcome to Android Central! Unfortunately, a factory reset wipes the device. Hopefully you had contacts and calendar events synced with Google, rather than saved to the device account, since if they were syncing with Google, they're safe in the cloud. But anything else saved on Internal Storage is gone. If you have a microSD card inserted, the files there are probably still ok.
In the future, if you're prone to forgetting important passwords, make sure you write it down and keep it safe somewhere at home, to prevent this kind of mishap.
