Signing in
A free Google sign-in, or a passwordless email link, gives you saving to the cloud, publishing, the asset library, and the AI features.
Open in the interactive manual →The interactive version has full-text search, a table of contents, and light/dark themes.
3dCMS signs you in with Google: one click, no password to manage. Signing in is free, and it turns on the parts that persist: cloud source scenes, publishing, the Asset Library, and the API token.
Sign in with an email link instead
Prefer not to use Google? Under the Google button, enter your email and choose Email me a sign-in link. We send a one-time link to your inbox. Click it and you land on a small page naming the address it will sign you in as, with one Sign in button; press that and you're in. The extra click is deliberate. Corporate mail scanners fetch every link in a message the moment it arrives, and a link that signed you in just by being fetched was being spent before you ever saw it, which is why some people found that the link never worked. It also means a link somebody else was mailed can't sign you into their account. The link expires in 15 minutes, and there's still no password to set or remember. An email sign-in gets you exactly the same features a Google sign-in does.
Or type the code from the same email
The same email carries a 6-digit code, and the sign-in card shows a field for it the moment the mail is sent. Typing the code signs in this browser, the one that asked. That matters when you started inside an app's browser (Instagram, Facebook, TikTok and the like open links in their own built-in browser): tapping the link in your mail app opens Safari or Chrome instead, a different browser with its own cookies, so the link signs in a window you were not working in and a /try scene built in the app would be stranded. The code keeps you where you are. Link and code expire together after 15 minutes, five wrong guesses retire the code, and using either one spends both.
Inside an app's browser the card also replaces the Google button with the reason (Google refuses to sign in there) and makes email the main action, with an Open in browser link for anyone who would rather switch. If nothing arrives after two minutes, check spam. When the mail provider itself is refusing to send, the card says that sign-in email is down for everyone and offers Google, rather than telling you to check an inbox nothing was sent to.
+tags, so you.name@gmail.com, youname@gmail.com and youname+3d@gmail.com are all the same inbox. 3dCMS now treats them as the same account too, whichever way you type it and whichever sign-in path you use: one library, one set of sites, one quota, rather than a fresh empty account per spelling. Addresses at other providers are matched exactly, because a dot or a + can genuinely mean something elsewhere.
