Can I set up my account so I can log in to online banking without their app?

The requirement that I authenticate with the app every time I want to use online banking on the PC has me worried that if my phone is ever lost or stolen or has a flat battery I am completely locked out of online banking.

I would love to be able to have an alternative MFA method that doesn't all hinge on that phone like a passkey, password manager, 2FA token, yubikey etc, or even using codes that go to my email or SMS or whatever. Anything other than using the app on the phone.
