Quick summary
Google Slides can be accessed without signing in if you have a shareable link to the presentation. Depending on the permission settings set by the file owner, you can view, comment on, or even edit the slides without a Google account.
Steps
- Get a shareable link to a Google Slides presentation — you need this link before you can access the file without signing in.
- Paste the link into your browser's address bar and press Enter to open the presentation.
- Check the permission access level granted by the file owner.
- Note that by default only commenting may be allowed without signing in.
- If the file owner has set anyone with the link as an editor, you can make full edits to the presentation without needing to sign in.
