Steam Guard is not standard TOTP: it emits five characters from a 26-symbol alphabet, and Valve does not hand out the shared secret.

—————
Where Steam hides the key
Steam Guard runs inside the Steam Mobile App. There is no “enter this text code” screen.
The shared secret exists on the device but Valve provides no supported way to export it.
Extracting it requires a rooted Android device or an iOS backup extraction — outside what a normal setup can do, and against Valve’s terms.
Not standard TOTPSteam derives five characters from the alphabet 23456789BCDFGHJKMNPQRTVWXY rather than six digits. A standard RFC 6238 generator cannot produce a Steam Guard code even with the right secret.

Questions
Can this tool generate Steam Guard codes?
Not from a standard setup. Steam uses a different alphabet and Valve does not expose the secret, so there is nothing to paste.
Why is Steam listed at all?
Because people search for it and every generator that claims to support it is glossing over the alphabet difference. Knowing it will not work saves an hour.
