I have had three of them on my keyring for years (one old personal, one newer personal and one for work) and even though they sometimes get lodged between the keys and a separate ring I have on the main ring none of them ever even got close to looking damaged (excluding some mild fading of the print on the oldest one).

You can store alternative 2FA methods and backup codes in a safe place just in case your YubiKey fails.
