Hosting Glossary
What is Two-Factor Authentication?
What Two-Factor Authentication actually means, minus the jargon — with the example that makes it obvious.
The short answer
2FA requires a second proof beyond the password — typically a time-based app code — so a stolen password alone no longer opens the account.
Below: the fuller explanation, an analogy that makes it stick, why it matters in practice, and where you'll actually meet it.

To read, obviously
App-generated TOTP codes beat SMS (vulnerable to number-porting); hardware keys beat both where supported. Recovery codes stored at setup are the answer to the lost-phone scenario.
Its coverage should follow privilege — hosting panel, client area, email and registrar first, since each can reset or redirect everything downstream of it.
A picture that makes Two-Factor Authentication stick
A second lock keyed to something you carry — the burglar with a copied front-door key still faces the deadbolt that copies can't open.
Analogies simplify, of course — but this one holds up well enough to reason with, and reasoning is the point of a glossary.
The practical stakes
Credential leaks are continuous background weather — 2FA converts every leaked or guessed password from incident into non-event, at the cost of one extra tap per login.
That's the test for every technical term, incidentally — not 'do I understand it fully' but 'do I know when it's the answer to my problem'. For this one, now you do.
Two-Factor Authentication in the wild
A password reused years ago surfaces in a breach dump and is tried against the hosting panel within hours — the login fails at the code prompt, and the incident is a log line.
Ordinary, once seen — which is the point: most hosting concepts are simple machinery wearing intimidating names.
How this shows up in your hosting
You'll meet it in the control panel and occasionally in a support conversation — usually already configured the right way. If this term made sense, the natural next reads are Brute-Force Attack, Phishing, SSH and Encryption.
Business email on your own domain is included, not sold back as an add-on.
A glossary from people who answer tickets
We think unexplained jargon is a service failure — this glossary is the support desk's accumulated translations, published where the search engines can hand them out.
Annual plans include your first year of domain registration on us.

FAQ
Your questions, answered
Is app-based 2FA really better than SMS?
Meaningfully — SIM-swap attacks intercept SMS codes; app codes never transit a network. SMS 2FA still beats nothing; app or hardware-key 2FA is the current standard of care.
What if I lose the phone with my codes?
Recovery codes (saved at setup, in your password manager) restore access; support identity-verification is the slower fallback. The setup-time habit of storing them is the whole insurance policy.
Which control panel do you provide?
cPanel — the industry standard, which means every tutorial on the internet matches your screen, your backups restore anywhere cPanel runs, and skills learned here transfer for life. Plesk and DirectAdmin options exist on specific plans for those who prefer them.
Do you monitor uptime, and what do you commit to?
We commit to 99.9% uptime and monitor continuously — not a marketing number but an operational one, with alerting that usually has us fixing issues before customers notice them.
Can I choose my PHP version?
Yes — PHP versions are selectable per site from the control panel, so a legacy application and a current one can live side by side. Extensions and per-site settings are adjustable in the same place, no support ticket needed.
Can I transfer a domain I already own?
Yes — transfers in are routine: unlock the domain at the current registrar, grab the auth code, and start the transfer from your client area. The remaining registration time carries over, and DNS keeps working throughout.
Do you include email with hosting?
Yes — mailboxes on your own domain come with every hosting plan, with webmail, IMAP/POP/SMTP access and spam filtering. Standalone email hosting also exists for domains whose websites live elsewhere.

Brute-Force Attack
A brute-force attack tries credentials repeatedly — passwords guessed by the thousand, or leaked pairs replayed.
SSH (Secure Shell)
SSH is the encrypted protocol for operating a server through a terminal.
Web Hosting
NVMe cPanel hosting with free SSL, migration and a free first-year domain.
Mail Filtering
Spam and virus filtering in front of any mailbox, anywhere it's hosted.
Planning to switch hosts? Grab the checklist here.
The steps that keep a site migration dull rather than dramatic: what to back up first, how to shift email across without losing a single message, when to touch DNS, and the two mistakes behind nearly every hour of downtime we come across.
Your site deserves better hosting.
Fast NVMe hosting, free SSL and migration, and real people on support around the clock — at prices that stay put.
