TcNo-Acc-Switcher VS RatScanner

This is what I use: https://github.com/TcNobo/TcNo-Acc-Switcher

Your observation is right. From own experience, Valve does closely monitor IP addresses on login. When anything seems fishy, Steam invalidates your saved credentials when you start it. Which requires you to type in your password and Steam Guard code again. This even happens if you use two Steam accounts on the same PC without special preparation (like not using an account switcher tool)

not really useful w/o "remember 2fa" feature, similar to this

If you want to take extra precaution then create a throwaway email and steam account. Switch between accounts with TcNo.

Use a throwaway email to create throwaway Epic accounts, and no worries. Then switch between accounts with TcNo.

Yep, check this out

Here’s the GitHub GitHub

This program can do it. https://github.com/TcNobo/TcNo-Acc-Switcher/releases/latest

https://ratscanner.com/ is a good utility that can also link to the tarkov tracker to help you know what you should keep and what you should pass on. And no, it is not against the rules.

Rat Scanner does that: https://ratscanner.com/

RatScanner combined with TarkovTracker.io made the same 3 tasks possible with one click in game.

Another project and the developer for it works with us! He made a great tool that you may find useful which doesn't require you from tabbing out of the game at all -> https://github.com/RatScanner/RatScanner

You could try using https://github.com/RatScanner/RatScanner as training wheels, but it won't replace players knowledge about actual item worth off the market and for barters/crafts.

Give your friends this https://github.com/RatScanner/RatScanner, then they can shift click the I sysmbol in the top left of an item description window and it will scan the name of the name and look up flea market price. It's pretty small and works if you just overlay over your game. Or like me if you have a 2nd monitor. Afik it's not against the TOS as it does not interact with the game in any way. It litterally reads the name off of your screen and then searches for it.

RatScanner for an in-game companion that scans items and gives you information like flea price/trader price or wether you need the item for quests/hideout or not.
