Change Security Key

[suzuyuzu]

My old phone, which has the security key for loggin in Mangadex, recently broke. I moved to a new phone, and I can't login "peacefully" each time. Every time I got logged out (around once a week, who knows why), I need to literally change my password via "Forgot my password". This is because even tho I have inputted the right password, it always prompts me to use security key, which my new phone obviously doesn't have. Does anyone know how to change the security key? I can't find it anywhere in the settings.

It prompts me to the same login page used to sign in. Then after I inputted my username and password, it asks for my security key, again.
