Hello, can anyone tell me that, If i will use phpbb for my website so is there any way to auto update my phpbb forum?
There isn't an automated system built in that I know of. You would have to download the update package or patch files and update the site. https://www.phpbb.com/downloads/?from=submenu#update
Also bare in mind any 3rd party module would only provide the upgrade after they have obtained it from PHPBB themselves. Probably best (and more secure) to go with manually updating it. If your hosting provider supports Softaculous check if the auto-upgrade feature is supported with PHPBB. If it does, PHPBB would be updated automatically once Softaculous has the update.
