How to uninstall Yubico Authenticator on Windows
Confirm another way to access accounts before removing Yubico Authenticator, and keep the security key available.
Quit the app
Close Yubico Authenticator and any work it is running, then use Task Manager (Ctrl+Shift+Esc) to check for its remaining processes.
Use its uninstaller
Open Settings › Apps › Installed apps, find Yubico Authenticator and choose Uninstall. Use the vendor uninstaller rather than deleting its program folder.
winget uninstall --id Yubico.Authenticator --exact
For this installation, winget invokes the registered removal method. It is not a separate cleanup of user data. Windows may ask for administrator approval.
Check the result
winget list --id Yubico.Authenticator --exact
Test-Path -LiteralPath "${env:APPDATA}\Yubico\Yubico Authenticator" -ErrorAction Stop
Read winget's result as well as its exit status: an explicit no-installed-package result concerns only this package, while a source, access or query error leaves the answer unknown. A successful Test-Path returning True means that exact location remains; False means it is absent. Neither result checks other paths. The commands do not delete anything.
What Mole lists
| Location | Item | Default |
|---|---|---|
%APPDATA%\Yubico\Yubico Authenticator |
Settings or app data; review before removal | Listed but not selected |
%ProgramData%\Microsoft\Windows\Start Menu\Programs\Yubico Authenticator |
Shortcut | Selected by default |
HKCU\SOFTWARE\Yubico\Yubico Authenticator |
Registry entry | Listed but not selected |
The selected local app data and settings key were removed or already absent, along with the shortcut. The empty Yubico parent folder remained. No security-key reset or credential deletion on a key was part of this test.
These defaults assume Remove data and settings with apps is off. Explicit Select all or Also remove user data can include the listed personal-data rows. Check the selection before confirming. Selected files that Mole removes go to the Recycle Bin; selected registry entries are backed up before removal. The vendor uninstaller has its own deletion behavior.
What this test covered
Recorded on 2026-10-20: Yubico Authenticator, version 7.4.2, machine-wide, MSI, winget package Yubico.Authenticator. The evidence comes from an ARM64 Windows test environment and a development build of Mole. It does not certify the current downloadable package or removal of real signed-in accounts, synchronized data or production projects.
