Are your apps also storing your credentials in a browser password manager on your phone automatically? In case you are having second thoughts about it, yes, turning off unwanted password syncing is one of the most effective ways to stop apps from quietly copying, storing, and sharing your logins across devices and services.
NOTE: Browser password managers are built in a way that they can access your social media applications and the websites you visit (also, once you give them the permissions to access the above). This should not be happening because once a browser password manager has access to your websites and apps, it will interfere with the lockscreen on each one of those, making you save your passwords and credentials to the manager, making it risky for your confidential information to be leaked/hacked. FastestPass’s dedicated password manager is a must!

Why Uncontrolled Password Sync Is Risky
Many browsers, phones, and apps now offer to “remember” or sync your logins, which sounds convenient but can create serious password sync security risks. This does feel like the easiest thing to do at that particular instant, but not everything that is easy must be done.
If one synced device is hacked or stolen, attackers can access all your saved credentials, leading to situations that feel like apps stealing saved passwords, even if it’s “just” misuse of a sync feature.
How Apps Sync Passwords Without You Realizing
- Browsers (Chrome, Edge, Safari) often enable sync by default once you sign into a Google, Apple, or Microsoft account.
- On both Android and iOS, system‑level managers can autofill logins for third‑party apps, effectively sharing the same stored passwords across many apps unless you change app permission password access.
This is why learning how to stop apps from syncing passwords is critical if you use shared devices, older phones, or work machines.
How to Turn Off Password Sync on Apps and Browsers
Here’s how you can turn off password sync on different apps and browsers easily:
1. Stop Google Password Sync (Chrome and Android)
To stop Google password sync, you need to disable both saving and syncing.
- In Chrome:
- Go to chrome://settings/passwords.
- Turn off “Offer to save passwords” and “Auto sign‑in.”
- Under “Sync and Google services” → “Manage what you sync” → turn off “Passwords” or disable Sync entirely.
- On Android:
- Open Settings → Passwords & Autofill → Google Password Manager.
- Turn off offers to save passwords and autofill, or switch autofill to a different manager.
These steps both stop apps from syncing passwords via your Google account and give you tighter control over where logins live.
2. Disable Password Sync on Android for Specific Apps
To disable password sync on Android per app, tweak Google Password Manager settings.
- Go to Settings → Password Manager → Settings.
- Under “Declined sites and apps,” you can manage which apps should never prompt to save passwords.
This helps prevent password sharing between apps that do not need automatic login access.
3. Turn Off iCloud Keychain Sync (iPhone/iPad)
If you use Apple’s iCloud Keychain and want a device not to hold sensitive logins:
- On that device, go to Settings → Apple ID → iCloud → Passwords and Keychain.
- Turn the Keychain off to stop that device from receiving synced passwords.
This is useful when repurposing an old iPad for family use, and you want to stop apps from syncing passwords to it.
Why Does “Stealing” Saved Passwords Happen
Often, apps stealing saved passwords are really apps or browsers pulling from the same synced store.
For example, a game or shopping app may request autofill from your system manager or browser, giving the impression it “knows” your credentials.
Key password sync security risks include:
- One compromised device is exposing every synced login
- Malware that exports browser‑stored passwords in bulk
- Family or coworkers on shared devices see autofill suggestions
This is why security pros recommend using a dedicated password manager rather than browser sync for high‑value accounts.
How to Prevent Password Sharing Between Apps
To truly prevent password sharing between apps, combine settings and good habits.
- Use a standalone password manager like FastestPass that lets you control which devices sync, instead of the browser or OS syncing everything by default.
- Turn off autofill for apps that don’t need it, and say “Never” when prompted to save passwords for low‑trust apps.
- Regularly audit your saved logins and delete credentials from browsers you don’t want acting as password stores.
This minimizes unseen app permission password access across your ecosystem.
Practical Checklist: Stop Apps from Syncing Passwords
- Browsers: Disable “Offer to save passwords” and “Auto sign‑in” (Chrome, Edge, etc.).
- Sync: Turn off password sync for your Google, Apple, or Microsoft account where not needed.
- Devices: Remove password managers from shared or risky devices, or log out of the sync account.
- Apps: Decline save prompts on untrusted apps; adjust autofill and keychain settings.
Following these steps shows exactly how to turn off password sync on apps without losing control of your main vault.
FAQs: Stopping Apps from Syncing Passwords
Turn off browser password saving, disable password sync in your Google/iCloud/Microsoft account, and use a dedicated password manager that lets you choose which devices sync. Most of the time, “apps stealing saved passwords” means they are using system autofill or browser stores you approved earlier, not secretly reading them—though malware can extract those stores if a device is compromised. Open Chrome or Android settings, go to Google Password Manager, disable “Offer to save passwords” and “Auto sign‑in,” and in sync settings turn off “Passwords” or sync entirely to stop Google password sync. Disabling sync usually stops future syncing but doesn’t always delete stored data; if you want a clean slate, you must manually remove saved passwords from that browser or device. Password managers are generally safer, offering stronger encryption, better control over which devices sync, and less risk of silent sharing between apps or browsers.
Conclusion
Uncontrolled syncing turns every phone, tablet, and browser into a copy of your digital keys, multiplying your attack surface. By learning how to stop apps from syncing passwords, how to stop Google password sync, and how to manage app permission password access, you keep convenience without sacrificing security. A dedicated password manager plus strict sync rules is the safest long‑term setup.
