How to save your passwords using NFC tags?

Question

Computer networks

A couple of days ago, I installed a new firmware on my smartphone. When all the steps were completed successfully, it was necessary to download all those applications that I often use.
It was also necessary to log in to them, which caused me some difficulty, since I try to come up with passwords as complex as possible.
After a couple of three hours, I finally completed what I started, and decided to think. Is it possible to upload a text document, which will contain logins and passwords from all my accounts, to an NFC tag, and at any time by scanning it through a smartphone, receive information about the login data for a particular account?
This is a convenient and practical solution for me.
The only question is, is it possible to implement such an idea? And how to do it?

Answer 2

Most NFC tags have only 64 bytes of memory, although there are models with 1kb, for example.
Isn't it better to use a password manager? And authorization in it can be done even through NFC, even by fingerprint, even by voice.
