If you remember one security rule from this site, make it this one: your password belongs on the official app or website of that platform — nowhere else. Ever.
The two kinds of “login”
Safe: a third-party tool redirects you to the platform’s own login page (the address bar shows instagram.com, accounts.spotify.com, etc.), you log in there, and the platform asks whether to grant the tool limited permissions. Your password never touches the tool.
Dangerous: the tool shows its own username/password boxes and asks you to type your credentials directly into it. The moment you do, that app owns your account — regardless of what it promised.
Credential-harvesting is the entire business model of most “free followers”, “who viewed my profile”, and “auto-liker” apps. Your login gets used to follow-bot others, send spam, or gets resold. Our breakdown of how follower apps really operate shows where those logins end up.
The 5-second check before any login
- Look at the address bar. Is this the platform’s real domain, or the app’s own page?
- Ask why it needs full login. Legit tools use official permission systems with limited scopes.
- Check what it wants to do. Anything that wants to post, follow, or DM “on your behalf” deserves deep suspicion.
If you already typed it somewhere
- Change your password right now, from the official app
- Turn on two-factor authentication
- Review and remove unknown sessions and connected apps in security settings
- Check whether your account follows strangers or sent messages you didn’t write

What about password managers?
Different thing entirely — a password manager stores your passwords locally/encrypted and fills them on the correct official site. That’s the opposite of typing them into a random app.
