While this Unlimited PS4 / PS5 Game Sharing Method is currently active complete with a guide and demonstration video below, before getting too excited keep in mind the loophole will inevitably be patched and closed by Sony as was done with previous PS4Scene and PS5Scene gamesharing methods... so NOT worth the risk in attempting them for most users. 
Update: As expected, this method has now been patched and no longer works.
Proceeding all the early PS4 ModChip-Based GameSharing Methods and PSN Account-Based PS4 GameSharing Methods, here are some more previous PS4 / PS5 GameSharing Methods for reference also sorted by date with the oldest first:

New unlimited game share method (PS4 / PS5):
1. Log in to your account and go to the Divas section
2. Get the name of the relevant device (PS4 or PS5) and change it
3. Change until you get an Error Has been Occurred
4. Sometimes the account may not give an error, in which case at least 15-20 times the name of the account will be randomly tested on the console to be active.
5. If the account is not active and does not give an Occurred error, then click on the account on a console like PS5 that has the capacity and get active and de-start. Finally, start changing the name of PS4 and repeat the above steps.

Be careful with my unlimited sharing account method on PS5, now if you click on any profiles 'hacked' on your PS5, all the games are immediately locked.
You need .rif for get launched I think, so you need to have the games on your account.
Update #2: GameSharing v3 PS4 by @freeplex
Today I'd like to share one piece of information I've learned a long time ago on the PS4 gamesharing method. This has been working for a long time, like a couple of years now.

Unlimited Refund: Critical PSN Refund Abuse via Family System – Financial and Security Risk
The reason this abuse is possible is that when someone purchases a game through a child account, no transaction is recorded in the parent account. Likewise, when a refund is issued, there is no record of the refund in the parent account either.
This means that neither the purchase nor the refund appears in the parent account’s history, making it impossible for Sony Support to detect any abuse linked to that account.
To exploit this loophole, users create child accounts with a birthdate set to just one day before turning 18. After purchasing and activating games on a PS5 and switching the console to offline mode, they immediately request refunds the next day — once the account is technically considered an adult.
As a result, someone can create unlimited child accounts under the same parent account and repeatedly request refunds — without being detected.
This is a serious and large-scale abuse of the system that requires immediate attention.
