TrayAuth keeps your two-factor authentication codes one click away. Click the tray icon and a
panel slides out of the taskbar showing live TOTP codes; click a code to copy it, and the
clipboard clears itself twenty seconds later.
Accounts are added by typing the base32 setup key a site shows next to its QR image. The add
dialog previews the code your key produces, so you can check it against the site before saving.
Accounts are stored in %APPDATA%\TrayAuth, encrypted with Windows DPAPI and readable only by
your Windows account. TrayAuth makes no network calls of any kind, and there is no account to
create and nothing to sync. Because a DPAPI vault is bound to the Windows profile that wrote
it, TrayAuth can export every account to a JSON file plus a scannable QR image, so a backup can
be restored here or added to a phone.
Codes are generated per RFC 4226 and RFC 6238 and verified against the published RFC test
vectors for SHA1, SHA256 and SHA512, so they agree with any other authenticator app. Six, seven
and eight digit codes and custom periods are supported.
