Our two factor authentication uses standard TOTP codes, which can be used with any authenticator you want. You can use Authy, Google Authenticator, Microsoft Authenticator, Aegis Authenticator, or generate the codes from your password manager if it supports 2FA.
However, if you deleted the app, then it may be that the 2FA codes are gone too. The secret key used to generate the 2FA codes are stored in the app, and unless your app has (cloud) backups you can recover, the code generation key may be lost.
