First of all, you should be noted that There is no way to recover your information or turn off Encrypt Backup if you lose or forget the password. So you can’t use the backup without password. We can only recommend you 3 options: If someone else set up your device, try to ask them for the password; try with your Apple ID password; try the password you previously used for any Apple related services.
Besides, if your iPhone, iPad or iPod touch is running iOS 10 or earlier, you can’t reset the password. In this case, you can only try using an older iTunes backup or use an iCloud backup; But if your device is running iOS 11 or later, you can make a new encrypted backup of your device by resetting the password:
Step 1. Unlock your iPhone, iPad or iPod touch, go to Settings > General > Reset.
Step 2. Tap Reset All Settings and then you need to enter your iOS device passcode.
Step 3. Follow the steps to reset your settings. You can rest assured that it won’t affect your user data or passwords, but it will reset settings like display brightness, Home screen layout and wallpaper. Of course, it also removes your encrypted backup password.
Step 4. Now you are able to connect your iOS device to iTunes and create a new encrypted backup again. Please do remember the password you set this time.
Once again, even if you have reset the password, previous encrypted backups still can’t be used, it will only allow you to back up your current data using iTunes and setting a new backup password.
Of course, if you remember your iTunes backup password but afraid that you may forget it one day, you can remove iTunes backup encryption. To turn off iTunes backup encryption, uncheck the Encrypted backup box in iTunes and enter the password. It will remove iTunes backup encryption and next time you use the backup it won’t ask you for password.

If you are willing to pay for more space, $1/month for 50GB, $2/month for 200GB, and $10/month for 2TB, and the 200GB and 2TB plans can be shared with family. For me, the 50GB plan is enough to backup all my stuffs.
