Constant re-authorization requests for gdrive.

[Naroleptic]

Hi!

I have been using app.diagrams.net in chrome and keeping files in gdrive for years with no issues.

Since a number of months very frequently when I open a diagram - regardless if doing so in app.disagrams.net (open from gdrive) or from drive.google.com - open with draw.io, or even opening a chrome tab-group - I have to re-authorize it to access the file.

draw.io is installed for my default account in chrome and that is the same for gdrive (personal/gmail - not workspace).

This is a major hassle. I have been trying to solve it with the help of AI, but to no avail.

Any help with this would be much appreciated since I really like the tool itself and have A LOT of diagrams for various things over the years.

Cheers!

Summary: The user reports that app.diagrams.net repeatedly asks for Google Drive re-authorization when opening diagrams, despite having a long-standing setup. This likely relates to browser cookie/token persistence issues, possibly caused by Chrome's evolving third-party cookie policies, privacy extensions, or multi-account configurations.

📝 Additional Information Needed

To help us investigate this more effectively, could you please provide:

• Browser version: Exact Chrome version being used (e.g., Chrome 125.x.x.x)
• OS: Operating system and version (e.g., Windows 11, macOS Sonoma)
• Browser extensions: Whether any privacy/ad-blocking extensions are installed (e.g., uBlock Origin, Privacy Badger) that might block third-party cookies or OAuth flows
• Third-party cookies setting: Whether third-party cookies are blocked in Chrome settings, as Chrome has been rolling out changes to third-party cookie handling which could affect OAuth token persistence
• Multiple Google accounts: Whether multiple Google accounts are signed in simultaneously in Chrome, which can cause authorization conflicts
• Incognito/profile details: Whether this happens in a specific Chrome profile, and whether it also happens in a fresh/incognito profile

We also have some questions:

• Do you have third-party cookies blocked in Chrome? Recent Chrome updates have been gradually restricting third-party cookies, which can interfere with Google Drive authorization persistence. Try going to chrome://settings/cookies and ensuring third-party cookies are allowed, or at least add exceptions for app.diagrams.net and accounts.google.com.
• Are you using any browser extensions that manage cookies, block trackers, or enhance privacy (e.g., uBlock Origin, Privacy Badger, Cookie AutoDelete)? These can delete or block the OAuth tokens that draw.io stores.
• Do you have multiple Google accounts signed into Chrome simultaneously? If so, does the re-authorization happen when your default account in the browser differs from the account that owns the diagrams?
• Have you tried revoking draw.io's access entirely from your Google Account permissions (https://myaccount.google.com/permissions), clearing your browser cache/cookies for diagrams.net, and then re-authorizing fresh?
• Does this issue persist if you try in a brand new Chrome profile with no extensions installed?
