The useful frame is not "is this secure" but "what does an attacker get if this one thing goes wrong, and how quickly would we know".
This piece walks through how we think about it at Paycux, what we have changed our minds about, and where the sharp edges are.
General best practices
That brings us to general best practices. Detection beats prevention when prevention is uncertain. If you cannot stop a class of abuse outright, make sure it produces a signal loud enough that someone sees it the same day.
Blast radius is the metric that actually matters. A credential that can read one organization's data is an incident; the same credential scoped to every organization is a company-ending event, and the difference is a design decision made months earlier.
Proper session management
Consider proper session management. Rotate on a schedule, not on an incident. A rotation path that has been exercised is a routine change; one that has never been used is an outage waiting for the worst possible moment.

- Scope credentials to the smallest useful blast radius
- Alert on the abuse you cannot prevent
- Exercise the rotation path before you need it
- Log the decision, not just the outcome
Ensure authentication comes from a trusted identity provider
That brings us to ensure authentication comes from a trusted identity provider. Detection beats prevention when prevention is uncertain. If you cannot stop a class of abuse outright, make sure it produces a signal loud enough that someone sees it the same day.

Require Multi-Factor Authentication (MFA)
Require Multi-Factor Authentication (MFA) deserves its own treatment. Blast radius is the metric that actually matters. A credential that can read one organization's data is an incident; the same credential scoped to every organization is a company-ending event, and the difference is a design decision made months earlier.

Complement SSO with automated provisioning
Consider complement sso with automated provisioning. Rotate on a schedule, not on an incident. A rotation path that has been exercised is a routine change; one that has never been used is an outage waiting for the worst possible moment.

Replace email verification with domain verification
Replace email verification with domain verification is where this gets concrete. Blast radius is the metric that actually matters.

Dynamically hide the password field

Where this leaves us
The pattern repeats across every system we have looked at: the hard part is not the mechanism, it is keeping the mechanism honest as the surrounding assumptions change.
If you are working through the same problem and want to compare notes, the docs cover the mechanics and the console shows the behaviour on your own data.
