What is authentication?
The process by which a system verifies who you are — through a password, a code, a fingerprint or a combination — before letting you in.
Every time you type a password, receive a code by text or place a finger on a sensor, you are being authenticated: proving your identity to a system. It is worth separating from its close relative, authorisation. Authentication answers who are you; authorisation answers what are you allowed to do. The bookkeeper and the managing director authenticate in exactly the same way but see entirely different screens. For your company's applications, the way authentication is designed decides two things at once. How exposed you are, because simple reused passwords remain the classic route into business accounts. And how smoothly people work, because a clumsy login repeated across ten applications burns patience every single day. The reasonable current standard for a mid-sized business: unique passwords held in a password manager, a second factor enabled on everything that matters, and single sign-on with the company account once you are running several internal applications.

Why it matters for your business
Company accounts protected at the source
Solid authentication — unique passwords plus a second factor — blocks the majority of attacks, nearly all of which begin with one compromised account.
Role-based access instead of everyone seeing everything
Once identity is verified, the application can open exactly what each employee needs, so the sales team never wanders into payroll data.
Genuine traceability of actions
When everyone works under their own account, the history shows who changed what — indispensable during errors, disputes or an audit.
Frequently asked questions
What is the difference between authentication and authorisation?
Authentication verifies your identity; authorisation verifies your rights. A well-built system treats them separately: the same login mechanism, but different screens and permissions depending on the role attached to the account.
Staff complain about too many passwords — what is the fix?
Single sign-on. People log in once with the company account, typically Google Workspace or Microsoft 365, and reach every connected application from there. Fewer passwords to forget, and when someone leaves you cut access in one place instead of twelve.
Is fingerprint or face authentication safe for business use?
Yes. Biometrics on modern phones never leave the device; they unlock a local cryptographic key instead. Combined with device possession as a second factor, the result is both safer and faster than a typed password.
