Hello,
The passkey for logging into my Salesforce-account isn't working (button doesn't react, in the correct browser) and the admin is also not able to create a temporary verification code (issue there as well?)...
I tried creating a case for support, but that required logging in to the Salesforce-account...

The fix is the temporary verification code path — it bypasses the broken passkey entirely (log in with username and password, then enter the code at the MFA prompt).
Two things are likely blocking your admin:
1) The admin needs the Manage Multi-Factor Authentication in User Interface permission. Without it, the Generate option for a temporary code does not appear — that is usually why an admin cannot create one. Grant that permission via a permission set to any admin, then: Setup, Users, open the locked-out user record, click Generate next to Temporary Verification Code, and set an expiry (1 to 24 hours).
2) Once you are in with that code, disconnect the broken passkey on your user record and register a fresh MFA method. That same admin permission also lets them disconnect your passkey for you.
On the case catch-22: a Support case can be logged by any other admin in your org who can still log in — it does not have to come from your locked account. If literally no one can get in, that is the break-glass scenario and you would reach Salesforce Support through your org account contact.
