Hi! A verification loop caused by automated security usually means the site/app thinks your traffic looks risky or “automated” (even when you’re a real person). The result is a cycle like:
login → security check → CAPTCHA/2FA → back to security check or “Checking if the connection is secure…” forever.

We’ll keep this low-risk: no repeated code attempts, no sketchy “bypass” tools, and no account changes that can trigger a stronger lock.

Tell me what you see (your words are best):
1) What service is it (Google/Microsoft/Meta, banking/KYC, e-commerce, streaming, etc.)?
2) Where does it happen (phone app, desktop browser, smart TV/console, work laptop)?
3) What’s the loop screen text: “verify it’s you,” “unusual activity,” “try again later,” “verify you are human,” “CAPTCHA,” or “MFA required”?

That pattern fits bot-detection / web application firewall behavior. The check tries to set a clearance cookie or run a JavaScript challenge; if that step fails (or gets blocked), you get stuck in an infinite verification loop.

Common causes we can safely test for (without “hacking around” anything):
• Cookies/storage blocked: the challenge can’t store its pass token, so it restarts.
• JavaScript blocked or modified: privacy extensions, strict tracking protection, or browser settings can break the challenge flow.
• VPN/proxy/IP reputation: shared VPN exit nodes can look like automated traffic and keep triggering checks.
• Network filtering: DNS/ad blockers or secure DNS can block required endpoints.
• Device fingerprint mismatch: frequent changes (user-agent spoofing, anti-fingerprinting settings) can look suspicious.

Quick clarifiers before you try anything:
1) Are you using a VPN, proxy, iCloud Private Relay, or “secure DNS” feature?
2) Any ad blockers / script blockers (uBlock, NoScript), anti-tracking, or “privacy browser” mode?
3) Does it fail on both Wi-Fi and mobile data, or only on one network?

That’s actually a helpful “signal”: if mobile data works sometimes, it points to environment (network/IP + browser settings) rather than your account credentials.

Here’s a safe way to isolate what automated security is reacting to, with minimal retries:

Controlled test A (browser/session):
• Use a fresh private/incognito window
• Temporarily disable only the extensions that affect scripts/cookies (ad/script blockers, anti-tracking) for that site
• Keep cookies enabled for the site (at least first-party storage) so the challenge can save its clearance token

Controlled test B (network):
• One attempt with VPN OFF
• If you must use VPN normally, do not toggle it repeatedly during the same session (that can look like automation)

Also: please avoid repeated CAPTCHA attempts in a row. If the system decides you’re “high risk,” it can escalate to more aggressive checks or temporary blocks.

When it loops, do you ever see a quick flash like you got through (page loads for a second) and then it bounces back, or is it stuck on the challenge page only?

That “loads briefly then bounces back” is classic for “token not sticking.” The page challenge succeeds, but the browser/device can’t keep the session cookie or the trust signal, so the automated security layer starts over.

On the Microsoft side, repeated puzzles/MFA prompts can be triggered by similar categories: risk signals, session persistence, device compliance policies, or sign-in frequency settings in a managed environment.

Let’s keep it practical and safe by checking the cross-platform basics first (no account security edits yet):

1) Cookie/storage sanity: If third-party cookies are blocked globally, some sign-in flows and security challenges can behave oddly. We’re not “opening everything,” just confirming whether the challenge can store what it needs.

2) Browser protection features: Tracking protection on “Strict,” script blocking, or secure network features can break challenge scripts.

3) Network reputation: VPN exit nodes, shared office IPs, or certain DNS filters can be flagged as “high automation.”

4) Cooldown/rate limits: Many systems escalate checks after repeated failures. When that happens, even correct actions can loop until the risk score calms down.

For your work laptop: is it managed (company device with policies/EDR), and does it happen only on that device?

Your instinct is right: rapid retries + VPN toggles are exactly what automated systems interpret as suspicious or automated behavior. You don’t need to “prove harder” — you need fewer variables.

Here’s the low-risk logic I recommend (diagnostic, not a guaranteed fix):

• Stop looping attempts when you see “try again later.” That message often indicates a cooldown window. More attempts can extend it.

• Pick one clean path and keep it steady: same browser profile, same network, VPN OFF for the test, and no switching devices mid-flow.

• On managed devices: some security software intercepts web requests or modifies scripts. That can break CAPTCHA/MFA handoffs or prevent cookies from persisting. You may need your IT team to confirm whether web filtering or “secure browsing” features are interfering — but you can still collect evidence safely (timestamps, exact prompt text).

If you’re seeing a CAPTCHA loop on a specific website, note whether it happens in multiple browsers on the same network. If it does, that points more strongly to IP reputation or DNS filtering than a single browser setting.

Great question — “vague” is normal with automated security, so the trick is to capture context instead of just one image.

A useful note pack looks like this:
1) The exact message text (“verify you are human,” “checking if the connection is secure,” “solve this puzzle,” “try again later”).
2) Timestamp + timezone and whether it repeats immediately or after a short success.
3) Device + environment: browser name/version, VPN on/off, extensions that affect scripts/cookies, DNS/ad-blocking, and whether it’s Wi-Fi vs mobile data.
4) Outcome of one comparison test: same device on hotspot, or same network in a clean browser profile.

That’s enough for support/IT to see whether it’s likely session persistence, IP reputation, web filtering, or a cooldown — without you taking risky steps.

Exactly. Automated security responds best to “boring and consistent.”

If one clean attempt works, that tells you the loop is environmental. If it still loops in the clean attempt, that’s also useful — because you can escalate with proof that it’s not just an extension or a messy browser profile.

And one more safety reminder: never use “CAPTCHA bypass” tools or random browser plug-ins claiming to defeat verification. Those often create more risk (and sometimes expose accounts). Stick to controlled diagnostics and official support paths.

That’s the right approach. If anything changes — the challenge switches from CAPTCHA to MFA, the “try later” message appears/disappears, or it works on hotspot but not on Wi-Fi — those details are gold for narrowing down the cause without risking a lockout.
