I want to have multiple accounts

Created at spa doing.

I want to have multiple accounts like SNS like Twitter.
I want to switch my account as soon as possible by clicking the account icon.
Currently, you need to log out and log in repeatedly to switch accounts.
Is account linking the only solution?
Once you log in with the account link, don’t you log in with other multiple accounts? This is a concern.
Best of all, you want to decide which accounts you have for each device. Each device and account requires a login.
Managing spa As Api has limitations and security issues, I think a back-end Api is necessary. Is it possible to do this with the management Api meta _ data?
In that case, what should I store in meta _ data?
