I have to disagree with the Authy recommendation. I switched to Authy a few years ago, but it was nothing but painful and I have recently migrated away from it. For a long time the "TouchID Prompt" was slow and buggy, but that does appear to be fixed now.
The real pain point is that it managed to corrupt one of my keys (how??) and the app tries to get me to backup my keys to their servers with multiple popups (which I cannot disable) prompting me to backup every time I use the app. I don't know why they are so determined to get hold of my OTP keys, but it isn't happening.
I'm currently using an app called "OTP Auth" and it seems quite nice, and is quick to use.
