Passkeys on TikTok no longer working

Hi, I have a problem. I have alternate tiktok accounts for when mine gets banned and they all have passkeys on them since that’s just easier. and before like 2 months ago passkeys worked fine and whenever I would go to the login page all the passkeys would appear, now they just don’t show up. This is a problem because I need these other accounts that I don’t remember the password to. Any suggestions??
