Microsoft FORCED account migration

[PrivacyOverProfit]

As we all have noticed microsoft has decided to force every and all minecraft players
to mirgate their mojang accounts to microsoft accounts.
I have not and will not migrate my account.
For those who ask why, it's simple.
Microsoft has no respect for privacy and i care about my privacy.
Dont be annoying with dumb questions or statements, thank you.

I have been trying to find a way to bypass the account migration.
The only solution i found for now is the tekkit launcher.
It allows me to login with my mojang account, minecraft works perfectly.
However i always used optifine, and a shaderpack and some sound mod.
For that i need to use fabric.
Is tekkit compatible with fabric?
Are there other launchers that support mojang login over microsoft login?
