Roblox

Roblox OAuth2 (OIDC-shaped userinfo). No PKCE, no id-token direct sign-in.

Configure

from better_auth import BetterAuth
from better_auth.oauth.providers_ext import Roblox

auth = BetterAuth(
    secret=...,
    social_providers={
        "roblox": Roblox(client_id="…", client_secret="…"),
    },
)

Or name-keyed (no import):

auth = BetterAuth(
    secret=...,
    social_providers={
        "roblox": {"client_id": "…", "client_secret": "…"},
    },
)

Options

Field	Type	Default	Notes
client_id	str | list[str]	required
client_secret	str	required

All shared ProviderConfig options apply.

Notes

• Default scopes: openid profile.
• Register {base_url}{base_path}/callback/roblox as the redirect URL on the Roblox OAuth app.
• The authorize URL carries prompt=select_account consent by default (default authorize_params).
• Roblox never returns an email: email is filled with preferred_username as a placeholder and email_verified is always False (matching TS). Display name prefers nickname.
