Starting in late 2021, certain Miiverse clone developers have created various authentication protocols. Users sign up for these services, and can use their accounts on them to sign up for different websites, including various Miiverse clones.

Project Silver

Project Silver was an inactive service created by Rix in December of 2021. It was initially hosted under prsilver.cf/login.php, for the purpose of signing up for the Miiverse clone Silver Club. There was no public method for creating a Project Silver account,  and users were only able to sign up if they were given sign up codes provided by Rix.

Prior to December 20, 2021,  Project Silver could be used to access the social media service writable.

On December 20, 2021, Project Silver was shut down alongside Silver Club. According to Rix and Term, the domain provider shut the site down for no given reason.

On January 8, 2022, Project Silver was brought back under gallery-ctr.ar.nf.

As of February 2022, Project Silver has been made inactive. The Project Silver page implies that the service was coming back in 2023.

As of April 2022, according to Rix, "...any plans regarding Project Silver or Silver Network has all been cancelled, as I'm working on a replacement project". Rix stated that Project Silver has been shutdown permanently, and that a successor was planned. This successor would be known as Riiset.

Terminal Network

"Terminal Network is the new way to centralize your services. Say goodbye to all your extra passwords and use one password as a key to all of your games, apps, sites, and more!"

Terminal Network was a service created by Terminal (also known as Term) on December 12, 2021. It is an authentication system based off of Project Silver. It is currently hosted under grapesu.webs.nf, a link previously used for a Grape rehost.

The purpose of Terminal Network is to serve as an authentication system which can be used across multiple services, mainly Miiverse clones. It was first tested on CloneMii, where users could request Term to manually merge their preexisting CloneMii account to their Terminal Network account. On December 13, Terminal Network was implemented on bruhclone, and a form was put out by bruhdude in order for users to link their Terminal Network ID (TNID) to their bruhclone account.

On December 17, Term implemented a tool that allowed users to automatically merge their Terminal Network account with their CloneMii account.  At first, the tool could only be used if their Terminal Network username matched their CloneMii username.  The next day, the tool was updated so that it could change the user's CloneMii username to match their Terminal Network username after authorizing.

As of April 2022, in a conversation between Terminal & Rix, Terminal said "Terminal Network should just die out", stating that it is shutdown forever.

Riiset

"Riiset your way to login. Say goodbye to tons of password, say hello to a centralized place!"

Riiset was an authentication system created by Rixy on April 20, 2022. It was based off of Project Silver and designed to be its successor. It was hosted under rixynet.webs.nf.

According to Rix, Riiset was significantly more secure compared to its predecessor.

As of July 2022, it is no longer active.

Blender Network

Blender Network was an authentication system created by bruhdude under ac.bruhdude.webs.nf/login.php. It was used for bruhclone. Users were unable to sign up for Blender Network. As of July 2022, it is no longer active.

authentikitty

authentikitty is an authentication system created by bruhdude, released under rebooted.link on July 14, 2022. Since bruhclone shared this domain, authentikitty replaced bruhclone upon its release. Its page states that it gives users access to "all of bruhnet", which includes bruhclone, Noted (a service that shut down a month prior), as well as another service known as Centerstage. Users are unable to sign up for the site, as the "Sign Up" button links to a Wayback Machine snapshot.
