I just disabled passwordless, cleared the Chrome cache and cookies, then set up passwordless, logged out and in. It prompted me for a TouchID, but then getting to a password field, it prompted me for my LastPass master password and only gave me up to 24 hours for not re-prompting log in.
Hello@ @User17070145017453971122
Welcome to the LastPass Community.
We apologize for the issues you have been experiencing. I checked the logs and they show that the LastPass MFA is failing you. Please disable passwordless, clear cache and cookies and set it up again on your device. Once you do that log out and then log back in and test it out.
Please let us know if there is something else we can do for you.
Greetings!

If Passwordless is set up but you're still getting prompts, check if "Re-prompt for master password" is enabled in your LastPass settings. Also, ensure your device/browser is recognized and that Passwordless is fully verified in your account.
