First: which HarmonyOS are you on?
This determines most of what follows, and the two are very different:
| HarmonyOS 4.x and earlier | HarmonyOS NEXT (5.0+) | |
|---|---|---|
| Underneath | Built on Android | Pure HarmonyOS; no Android app compatibility |
| Autofill | Works | Not available |
| Which build you install | The Android one | The HarmonyOS one |
Check under Settings → About phone. Most Huawei phones in use today are 4.x or earlier, where autofill works normally.
Autofill
HarmonyOS 4.x and earlier: works, with one extra step
Set it up the Android way — see the autofill guide. Two things specific to Huawei:
- The background pop-up permission must be on. Without it, tapping to fill does nothing at all. It lives under Settings → Privacy → Permission manager → background pop-up; the quickest way there is to search settings for 后台弹窗. See troubleshooting autofill.
- Huawei's secure keyboard covers the suggestion popup. On password fields the system may force its secure keyboard, which hides the fill prompt. Turn the secure keyboard off in keyboard settings, or use accessibility-based recognition instead.
- Suggestions do not appear above the keyboard. Chinese Android systems generally do not support inline suggestions, so KeyMe Pass falls back to a floating panel — a different position, the same function.
HarmonyOS NEXT: not yet supported
HarmonyOS NEXT has not opened the system APIs autofill depends on, so no password manager can fill across apps there. This is a platform limitation rather than something specific to KeyMe Pass.
Until then, copy from the app and paste. We will follow once the APIs open up.
Passkeys
Support comes down to the Android version, not whether Google services are present — a common misconception.
| Your device | Create and sign in? |
|---|---|
| Android 14 or later with the system credential framework | Yes |
| Android 13 or earlier | No |
| HarmonyOS NEXT | No |
The reason: for a third-party app to act as a passkey provider it needs a system framework introduced in Android 14. Below that version the mechanism simply does not exist.
Most Huawei models today run an Android base below 14, so creating and signing in with passkeys is not available on them.
Synced passkeys are still visible
Passkeys you created elsewhere — on an iPhone or a newer Android phone — appear in the list on your Huawei device once sync is on. You can view and manage them; you just cannot sign in with them here. The app says so at the top of the list.
Membership and subscriptions
- The HarmonyOS build purchases through Huawei's in-app payment.
- ⚠️ Cancelling has to happen in Huawei's own account area, not in our app: AppGallery → Me → Manage subscriptions.
- If you have purchased on more than one platform, those subscriptions are independent and each has to be cancelled separately.
For current plans and prices, see the Membership screen in the app or the pricing page.
Other
Network errors while the phone is clearly online
Huawei systems gate network access per app. Check Settings → Apps & services → App management → KeyMe Pass → Data usage, and allow both mobile data and Wi-Fi.
App updates
The HarmonyOS build updates through AppGallery; there is no in-app update check.
These all work normally on Huawei
So you are not left wondering:
- Fingerprint and face unlock
- Local encrypted storage and every vault feature
- Multi-device sync and cloud backup
- Import and export
- The browser extension (it runs on your computer, independent of the phone)
