With visitor sharing, your users can invite non-Google users to collaborate on files as visitors, using PINs (Personal Identification Numbers) to verify their identity. This allows you to always see who has access to your organization’s files and folders if you share externally.
How it works
Once turned on for your organization, users will be able to share to visitors in the same way they share to Google users. People with non-Google accounts will receive an email invitation to collaborate on the shared file or folder. The user has 7 days to verify their identity with a PIN to collaborate on the shared file or folder. If the user needs to collaborate longer than 7 days, they can use the original link from their email to verify their identity again.
- Once authenticated, visitors can view, comment on, suggest edits to, and directly edit files and folders. If a visitor has edit access, they can re-share the file with another Google user.
- Visitors cannot create or own files and folders.
- Visitors can delete their visitor session.
Visitor accounts can be seen in the sharing dialog, where you can change or revoke their access just like any other collaborators.

Known issues and limitations
Some sites that use a Google sign-in may show a user's visitor session in the account switcher, or when they select their picture on the upper-right side of the screen. Visitors cannot, however, use a visitor session to sign in to Google services other than Drive, Docs, Sheets, Slides, and Sites.
We have a limit on the total number of visitor sessions that can be created. If we hit our limits, users may see sharing errors.
This feature applies to the web version of Google Drive, including files shared through My Drive and shared drives, but it will not give non-Google users access to documents in downloaded clients including Drive File Stream or Backup and Sync.
Administrators can upgrade a user’s visitor session to a Google Workspace account by creating a Google Workspace account with the same email address as the visitor session. Upgrading to a Google Workspace account retains the visitor session's collaboration history including document comments and edits.
To upgrade from a visitor session to a Google account with the same email address, a visitor will need to first delete their visitor session and then create a Google account.
Visitors cannot do the following:
- Upload or create content.
- Access the root folder of a shared drive.
- Be added to Google Groups.
- Edit Sites, but they can be Published Viewers of a Site.
