authbox.io does not allow embedding, so this is Google's rendering of the page.
Speed
Render-blocking requests
300 ms2 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.
Legacy JavaScript
150 ms · 22 KiBPolyfills for old browsers add 22 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 67 ms. During a long task the page ignores taps.
Reduce unused JavaScript
25 KiBAbout 25 KiB of JavaScript is downloaded but never used on this page.
1 third-party service on the page
1 third-party service load with your homepage (Cloudflare), adding 10 KiB and 11 ms of main-thread time.
Use efficient cache lifetimes
5 KiB2 files are served with short cache lifetimes, so returning visitors download them again (5 KiB).
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Mobile performance score: 99
99/100Your mobile performance score is 99. That is in Google's “good” band (90 and up).
Main-thread work: 0.5 s
A phone's processor spends 0.5 s on main-thread work while loading, 146 ms of it running JavaScript. That is comfortably low.
Server response: 2 ms
2 msYour server sent the HTML in 2 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

First Contentful Paint: 1.5 s

Largest Contentful Paint: 1.5 s
1.5 sYour largest element renders in 1.5 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “Your Keys. Your Identity. Unstoppable.”.
Total Blocking Time: 17 ms
17 msScripts block the page for only 17 ms while loading. Good is under 200 ms.
Time to Interactive: 1.9 s
1.9 sThe page is fully interactive after 1.9 s.
Images and page weight
About 0.06 g of CO₂ per visit
0.06 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.06 g of CO₂e: 6.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
1 checks passed
Page weight: 207 KiB in 18 requests
207 KiBYour homepage downloads 207 KiB in 18 requests on a phone: scripts 188 KiB (14), HTML 8 KiB (1) and stylesheets 8 KiB (1). That is a lean page.
Accessibility
12 text elements with low contrast
12 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
1 checks passed
29 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 30 WCAG 2.2 A/AA and best-practice rules on the phone render: 29 passed and 1 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No canonical URL
No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
No XML sitemap
No XML sitemap at https://authbox.io/sitemap.xml, so Google discovers your pages only by following links.
Only 4 internal links
The homepage links to only 4 pages on your own site, so visitors and crawlers find few routes into the rest of it.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is incomplete here.
4 checks passed
Meta description: 138 characters
Your meta description is 138 characters: “Manage passwords, OAuth authorizations, and AI agent access in one encrypted vault. Your credentials never leave your d…”.
One H1 headline
Your main headline reads: “Your Keys. Your Identity.Unstoppable.”.
Title: 55 characters
Your title is a healthy 55 characters: “Auth Box - Zero-Knowledge Password Manager & AI Gateway”.
robots.txt in place
robots.txt is in place.
AI search readiness
No Organization structured data
There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.
No llms.txt
There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.
2 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Text is in the HTML
Your server sends the page's text in the HTML (293 words), so crawlers that don't run JavaScript still read it.
Other pages
2 pages share a title
/ and /create all use the title “Auth Box - Zero-Knowledge Password Manager & AI Gateway”. Search engines can't tell which page to show for a search, so each competes with the others.
1 page without an H1
/create has no <h1> headline, so visitors and search engines get no clear main topic.
1 page with very little text
/create has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.
1 internal page checked
We fetched 1 page linked from your homepage and read each the way a search engine does.

Security and trust
1 broken link to your own pages
1 link from your homepage to your own site is broken, for example https://authbox.io/cdn-cgi/l/email-protection (404).
No Content-Security-Policy
No Content-Security-Policy header, the main browser-side defence against injected scripts.
Deprecated X-XSS-Protection
X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.
No security.txt
There is no /.well-known/security.txt telling researchers how to report a security problem to you.
6 checks passed
Served over HTTPS
The homepage is served over HTTPS (authbox.io).
Valid certificate (34 days left)
The certificate from Google Trust Services · WE1 verifies for authbox.io and is valid for another 34 days.
Protected from clickjacking
X-Frame-Options or a frame-ancestors policy stops other sites framing yours.
HSTS enabled
Strict-Transport-Security is set, so browsers always use https.
http:// redirects to https
http://authbox.io redirects to the secure version.
HTTP/2 and HTTP/3
The server speaks HTTP/2 and advertises HTTP/3, so browsers load many files over one connection.
Domain and trust
No CAA record
authbox.io has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.
Content and conversion
No social proof
No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
About 292 words of copy
The homepage carries about 292 words of visible text.
3 checks passed

2 calls to action

Analytics in place

Email authentication
DMARC is monitor-only (p=none)
DMARC is set to p=none, so mail pretending to be authbox.io is still delivered. Reports are on, so moving to quarantine is the next step.
No DKIM key on the usual selectors
We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.
Email authentication score: 60/100
Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.
1 checks passed
SPF in place (~all)
An SPF record lists your sending servers and marks other mail as suspicious (~all): “v=spf1 include:icloud.com ~all”.
Privacy and tracking
No consent tool detected
No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.
1 other company contacted
Loading the homepage contacts 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
1 checks passed
No known trackers before consent
