What is "-noreactlogin" and how do I use it?

[Fermoux]

I really do not like the new steam login UI and want to change it back to how it was before. I searched around on the internet and found people talking about "-noreactlogin" and saying that using it will revert the login UI to how it was before. But I don't really know what it is or where I'm supposed to paste it in.

Could someone who knows put tell me what "-noreactlogin" is, how to use it and if it's a bad idea to do it?

Have the argument outside of the citations. You don't want it in the actual path.

i.e.

"C:\Games\Steam\Steam.exe" -noreactlogin

NOT

"C:\Games\Steam\Steam.exe -noreactlogin"

-noreactlogin is a commandline launch option that Steam.exe accepts. The option disables the ReactJS based login window and system, and returns the old login window and system.

To use it, you need to run Steam.exe with this special commandline option.
The target file is the exe, followed by a space, followed by any commandline option chain.

In windows, you can edit any shortcut on your desktop's properties and insert this launch option into the target field in a similar way. (it will only do something with Steam.exe though)


-noreactlogin was a string discovered when someone decided to investigate the strings. It looked like a typical commandline option, some tested it and discovered what it did. This option is undocumented. Valve hasn't mentioned about it anywhere.

Its safe to use, if it is a good idea, depends on your situation. Valve will continue to turn the Steam Client into a full blown chromium based javascript app from the looks of it, which will eat a lot of RAM and other resources and possibly cause BSODs at this rate since they seem to push broken builds and features to release.
Using this option reduces some boot-problems and security problems currently, so it currently is in my opinion a good idea.
That said, using it may cause issues later; I'm not sure about that yet.
