Hey @VoltXtrem :waving_hand:

I feel your pain — that auto-linking behavior where Google silently attached your new number to all 7 existing accounts is one of the most frustrating (and least documented) things Google does. We did a deep dive into exactly this problem recently, so here’s everything that should help you going forward.

Why This Happened To You

What you experienced has a name — automatic number linking. When you added a new phone number to your device or used it near your existing accounts, Google’s detection system associated it with all accounts that shared the same device fingerprint, IP address, and cookies. It didn’t even need your permission.

Google uses multi-layered detection combining:

  • The phone number itself
  • Device fingerprinting (screen size, fonts, timezone, canvas rendering)
  • IP address
  • Cookies & session data
  • Behavioral patterns

:warning: As of February 2025
Google formally re-enabled device fingerprinting across all services. This is why simply using a “new” number on the same device/browser doesn’t help — Google already knows it’s you.

So your new number got burned because Google saw the same device + same IP + same browser cookies and thought: “Same person, let me link this number to everything they own.”

Immediate Fixes For Your Situation

1. Stop Using Phone Numbers for 2FA — Switch to Authenticator Apps

This is the single most important thing you can do right now:

  • Go to myaccount.google.com → Security → 2-Step Verification on each account
  • Add Google Authenticator or Authy as your 2FA method
  • Remove your phone number from 2FA (keep it only if forced for recovery)
  • As of May 2024, Google lets you add authenticator apps before enabling 2SV — no phone number needed first

:white_check_mark: Why this matters
SMS-based 2FA creates the exact same linkage as account verification. Authenticator apps create zero phone-number linkage. This alone stops future number burning.

2. Remove Phone Numbers From Accounts That Don’t Need Them

Go to each account → Security → Phone numbers → Remove where possible.

:warning: Heads up
Even after removal, Google retains the association internally for ~2 months (encrypted backups up to 6 months). Data tagged as “security & abuse prevention” may be kept indefinitely. But removing it still prevents future auto-linking triggers.

Going Forward — How To Not Waste Numbers Again

● The Nuclear Option: Use Workspace Admin Accounts

This is the real solution if you’re working on a project and need multiple accounts:

Managed accounts created through Google Workspace admin console NEVER require phone verification. Period.

  • Get a cheap domain (~$1/year from Namecheap/Porkbun)
  • Sign up for Google Workspace ($7.20/mo for Business Starter)
  • Verify domain via DNS records
  • Create as many user accounts as you need from the admin console — zero phone numbers required
  • You can also use Cloud Identity Free (up to 50 users, no Gmail but you get the identity/auth)

● If You Must Use Personal/Consumer Accounts

The 4–10 rule: Each phone number can verify approximately 4–10 accounts before Google blocks it. Your 2 numbers × ~5 accounts each = ~10 accounts is about right, so you were already at the limit.

What actually works for verification:

Method Reliability Notes
Family/friend numbers :green_circle: High Google officially suggests this — ask someone you trust
Landline via voice call :green_circle: High Select “Call me instead” — landlines work great
Prepaid SIM (different carrier) :green_circle: High AT&T/Verizon/T-Mobile/Jio all accepted — each counts as separate
Android device settings signup :yellow_circle: Medium Settings → Accounts → Add account often skips phone entirely
“Use email instead” option :yellow_circle: Medium Sometimes appears during signup — click it fast

What does NOT work:

  • :cross_mark: Google Voice numbers — explicitly blocked
  • :cross_mark: TextNow, Skype, any VoIP — detected and rejected
  • :cross_mark: Most eSIMs (Airalo, Nomad) — data-only, no phone number
  • :cross_mark: MySudo — VoIP-based, likely blocked

● Prevent Auto-Linking on New Numbers

This is specifically what burned you. When you get a new number, do this before touching any Google account:

  1. Use a completely different browser profile or device — don’t sign into the new number on the same Chrome profile that has your existing accounts
  2. Clear all cookies first or use a fresh Firefox container / Chrome profile
  3. Use a different IP — connect via mobile data or a different WiFi, not the same network your other accounts use
  4. Don’t add the number to any existing account until you’ve used it for the new account verification first
  5. Never add the same number to multiple accounts — use authenticator apps for 2FA on the rest

:white_check_mark: The Golden Rule
1 phone number = 1 Google account for verification. Use authenticator apps for 2FA on everything else. This is the only way to guarantee zero cross-contamination.

Browser Isolation Setup (So Sessions Don’t Bleed)

You’re probably managing all these accounts in the same browser — that’s how Google fingerprints you across accounts.

Option A — Chrome Profiles (Recommended):

  • Create a separate Chrome profile for each Workspace account
  • Each gets its own cookies, history, passwords, extensions
  • Assign different colors so you never mix them up
  • Create desktop shortcuts for instant access

Option B — Firefox Multi-Account Containers:

  • Install the Multi-Account Containers extension
  • Create a container per account (color-coded tabs)
  • Set “Always open Google in this container” per account
  • All containers run in one window — no juggling windows

Also: Don’t use Google’s built-in account switcher for anything critical. The /u/0/, /u/1/ indexes are based on login order, not specific accounts. Bookmark with [email protected] instead.

Summary Action Plan For You Right Now

  1. Switch all 7 accounts to authenticator app 2FA — remove phone numbers from 2FA
  2. Remove phone numbers from account recovery where possible
  3. Set up Chrome profiles — one per account, stop using the same browser session
  4. For your project: Get a cheap domain + Workspace subscription — admin-created accounts = zero phone verification forever
  5. If you need more consumer accounts: Ask family/friends for their numbers (Google officially supports this), or use Android device settings signup to sometimes skip verification entirely
  6. New number? Always use it on a fresh device/profile/IP first — never on the same browser that has existing accounts

Hope this helps you get unstuck :folded_hands: That auto-linking behavior is genuinely one of Google’s worst “features” and almost nobody documents it properly.
