Every review-reply tool, ours included, asks you to connect your Google Business Profile before it can do anything useful. That one click hands over real access to a business asset you depend on, and most owners approve it without knowing exactly what they just agreed to. Here is what that connection actually grants, what Google's own guidance says about vetting it, and a plain checklist to run before you connect anything.
The short answer
Connecting a review-reply tool almost always grants two things: permission to read your reviews, and permission to post replies on your behalf, through Google's official Business Profile API using an OAuth sign-in you approve. It does not, by default, let a tool delete your listing, change your hours or address, transfer ownership, or see unrelated accounts like Gmail or Google Ads. A legitimate tool asks for exactly the access it needs to do its one job, and lets you revoke that access at any time, either from inside the tool or from your own Google account settings.
What "connecting" actually grants
There are two different mechanisms people lump together as "giving a tool access to my reviews," and they work differently. The first is adding a person as a Manager inside Google Business Profile itself, the classic setup for an agency employee who logs in and edits the listing by hand. The second, and the one almost every AI review-reply tool uses, is an OAuth connection: you sign in with Google once, approve a specific set of permissions, and the tool's software, not a person, reads and writes through Google's official Business Profile API from then on.
- A typical OAuth request from a review-reply tool covers: reading your reviews and star ratings, posting replies to them, and identifying which locations belong to your account.
- It should not need, and a well-built tool will not request, access to your Gmail, Drive, Google Ads, Search Console, or the ability to delete your Business Profile outright.
- The access is tied to your Google login, not a password you hand over. Nobody at the company sees or stores your actual Google password.
Owner vs. Manager access
Google's own Business Profile guidance splits access into tiers, and the difference matters more than most owners realize. An Owner can edit everything, add or remove other people's access, and transfer or delete the listing. A Manager can edit the profile and respond to reviews, but can't remove the owner or transfer ownership. Google's guidance is direct about this: the fewer people who have access to your Business Profile, the less likely it is to be compromised, and it specifically recommends keeping the list of owners and managers to only who and what is essential.
For a review-reply tool, Manager-equivalent access, or the narrower OAuth scopes described above, is all that's needed. There is no legitimate reason a tool built to draft and post replies needs Owner-level control over your listing.
Red flags, per Google's own guidance
Google publishes its own advice on vetting anyone who wants access to a Business Profile, written mainly with agencies and marketers in mind, and it applies just as directly to software.
- Confirm the connection uses Google's official sign-in screen, not a request for your raw password
- Check that you keep your own Owner-level access after connecting a third party, exactly as Google's guidance recommends
- Get a plain-language explanation of what the connection reads and what it can post
- Verify any claim of being "Google-approved" separately: real Google staff use an @google.com address, never a generic contact form
- Approve an access request from an email or caller you didn't reach out to first
- Grant access before getting a clear, written explanation of the cost and the service
- Assume a tool can lock you out of or delete your listing: Google's policy states a third party can't access or remove your profile without your permission
- Leave a tool connected after you've stopped paying for or using it
The 6-point checklist
Whichever tool you're considering, ours included, run it through these six questions before you click connect:
- Does it use Google's official sign-in screen, or does it ask for your password directly?
- Does it state, in plain language, exactly what it reads and what it can post, not just a blanket "we access your Google account"?
- Can you see and revoke the connection from two places: inside the tool's own settings, and inside your Google account's own third-party access list?
- Does canceling the subscription actually remove the access, or does the connection quietly stay live?
- Is the pricing public, so you're not trusting a company you can't even evaluate on cost before granting access?
- Does the privacy policy say what happens to your review data and reply history after you leave, not just while you're a paying customer?
Check who has access right now
You don't need to take a vendor's word for what's connected. Two places show you the truth directly. Inside your Google Business Profile's own settings, the Users section lists every Owner and Manager with access, human or app, and only an Owner can add or remove entries there. Separately, your Google Account's own security settings, under "Third-party apps with account access" at myaccount.google.com, show every app ever granted OAuth permissions, exactly which scopes it holds, and a one-click way to remove any of them.
What we ask for, and what we don't
Since we build one of these tools, here's ours specifically, not as a pitch, but because an honest answer to "is this safe" has to include naming what we actually do. Connecting Resparo is a single Google sign-in, the same OAuth flow described above, never a request for your password. We store the access and refresh tokens that let us read your reviews and publish replies, encrypted at rest, and we never see or store your Google password itself. You can disconnect from inside Resparo at any time, and the tokens are deleted immediately, not just marked inactive. We don't sell review data, and we don't use it to train AI models without separate, explicit consent.
- Reads your reviews, ratings, and business details, nothing beyond what drafting and posting a reply requires
- Posts only the replies you approve, or the ones you've explicitly turned on Autopilot for, part of the same approve-or-automate split covered in full in our <a href="/blog/google-review-automation" class="LINK">google review automation guide</a>
- Never touches Gmail, Ads, Search Console, or any other Google product
- Access is revocable in one click, from inside Resparo or from your Google account directly
If you'd rather not connect anything yet, test the writing quality first with the free reply generator, no sign-in required, and decide whether to connect only once you've seen the output. When you're ready to see the full workflow, how it works walks through the connect-and-approve steps in order, and pricing is public, no demo call required.
The bottom line
The access a review-reply tool genuinely needs is narrow: read your reviews, post the replies you approve. Anything wider than that is worth a direct question to the vendor before you click connect. Google's own guidance and a five-minute check of your account settings are enough to vet any tool honestly, ours included, and the discipline is the same whether you connect Resparo, a competitor, or nothing at all: keep the access list short, know what's on it, and remove anything you're not actively using.
“The right amount of access for a review-reply tool is exactly enough to read a review and post the reply you approved, nothing that lets it touch anything else you've built.”
