New: sign in to ProGantt Flow with your Microsoft account

Until now, the only way into ProGantt Flow was a Google account. That worked for a lot of people, but not for teams that live in Microsoft 365, where every colleague already has a work account and asking them to use a personal Google login just to open a project plan is friction nobody needs.

So today we are adding Sign in with Microsoft. You can use a personal Microsoft account (Outlook.com, Hotmail, Live) or a work or school account from Microsoft 365. Google sign-in stays exactly as it was.

How to sign in with Microsoft

1. Go to app.progantt.com.
2. Click Sign in with Microsoft.
3. Pick the account you want to use in the Microsoft window. If you are signed in to more than one, you will be asked which one.
4. That is it. Your dashboard opens and you can create a project or open one that was shared with you.

The same button appears on the screen you see when you connect an AI assistant to ProGantt through the MCP connector, so you can authorize Claude, Cursor or VS Code with your Microsoft account too. The connector docs cover that setup step by step.

Why you might be asked to verify your email

In ProGantt Flow, projects are shared by email address. When someone shares a plan with ana@company.com, whoever signs in as ana@company.com gets access. That makes the email address the key to everything, so we need to be sure it really belongs to the person signing in.

Google always confirms that for us. Microsoft does for personal accounts, but work and school accounts are different: the address on the account is set by the organization's administrator, and Microsoft does not vouch for it. If we trusted it blindly, an address typed into the wrong directory could open projects that were meant for someone else.

So if your Microsoft account arrives without a verified email, ProGantt Flow shows a short Verify your email screen first:

• We send a one-time link to your address.
• You open it, come back and click I've verified my email.
• From then on you sign in normally. You only do this once.

If the email does not arrive within a few minutes, check your spam folder or use Send the link again. A Microsoft account without any email address cannot be used, because there would be nothing to share projects with. In that case, sign in with another account.

Already using ProGantt with Google?

If you have been signing in with Google and your Microsoft account uses the same email address, you do not end up with two separate accounts. The first time you try Microsoft, ProGantt Flow tells you that an account already exists for that address. Sign in once with Google, and your Microsoft login is linked to it. After that, either button opens the same dashboard, with the same projects and the same plan.

If your Microsoft account uses a different address from your Google one, they are simply two different accounts, each with its own projects. Projects shared with one address are not visible from the other.

What we receive from Microsoft

The same as with Google: your account identifier, email address and display name. We never see your Microsoft password. Microsoft does not send a profile photo, so your avatar shows your initial instead. The details are in our privacy policy.

Sharing with Microsoft 365 colleagues

This is where the change matters most. If your team works in Microsoft 365, you can now share a project with a colleague's work address and they can open it with the account they already use every day, without creating anything new.

Sharing works exactly as before:

1. Open the project's sharing settings from the dashboard.
2. Enter your colleague's email address and choose Editor or Viewer.
3. They sign in with Microsoft using that address and the project appears on their dashboard.

The Free plan lets you share with up to three people across all your projects; Pro removes the limit. If you are new to sharing plans, our guide on how to assign tasks to team members walks through setting up a team project.

Try it

Microsoft sign-in is live now at app.progantt.com. If something does not work as described here, use the support chat inside the app and tell us which kind of Microsoft account you used. Work, school and personal accounts behave slightly differently, and that detail helps us find the problem quickly.
