Why cookie login for fb but not for ig or x?

[shadowspinner2023]

So I’ve been testing some bought accounts lately across different platforms: Facebook, Instagram, and X. I noticed something kind of confusing and wanted to ask others here who’ve done this more than I have.
Every time I buy Facebook accounts, the seller always recommends logging in with cookies first, and only using the password later if really needed. But for Instagram or X accounts, even when cookies are included, most sellers say it’s fine to log in directly with user/pass.
Why is that? Does Facebook track new device logins more aggressively? Or is there something different about how those platforms handle session data?
Also, if I’m importing cookies, should I be doing that in a regular browser, or is it better to use some sort of fingerprinted setup? Just want to make sure I’m not burning accounts for no reason.
Would really appreciate some clarification on this. Thanks in advance.

Cookie login is safer for Facebook because their system links sessions to very specific fingerprint data - device, timezone, browser entropy, even font lists. Using the cookie allows you to resume that session without triggering a full re-evaluation of the environment.
Instagram and X are more tolerant of fresh logins, as long as the login environment isn’t drastically different. But if you're importing cookies on any platform, you should still use an antidetect browser (GoLogin, Hidemyacc, etc.) to replicate the original fingerprint. Otherwise, even valid cookies can trigger a mismatch and get the account flagged.

It helps to bypass security checks, always import cookies using an antidetect or fingerprinted
browser to mimic the original login environment.
