Example Code

import typer

app = typer.Typer()
update_app = typer.Typer()

@update_app.command()
def password(password: str):
  # update password
  pass

@app.command()
def user(email: str):
  # get user email
  pass

app.add_typer(update_app, name="update")

if __name__ == "__main__":
	app()

Description

I think that the pattern I want to achieve is pretty straightforward. I would like to be able to define subcommand to app, but force user to pass some argument before subcommand. In this example I want to have user to act as a selector of some particular user before I follow with subcommands. So my expected behavior is to be able to do:
python3 main.py user "test@test.com" update password "qwerty"

Currently it just show "update" as one of the commands of the main program.

Make user a Typer group with a callback, then put update below that group. The callback consumes email before the subcommand and stores it in the inherited context:

import typer

app = typer.Typer()
user_app = typer.Typer()
update_app = typer.Typer()


@user_app.callback()
def select_user(ctx: typer.Context, email: str):
    ctx.ensure_object(dict)
    ctx.obj["email"] = email


@update_app.command()
def password(ctx: typer.Context, password: str):
    email = ctx.obj["email"]
    # Call your update routine with email and password here.
    typer.echo(f"Updating user {email}")


user_app.add_typer(update_app, name="update")
app.add_typer(user_app, name="user")

if __name__ == "__main__":
    app()

This accepts your requested shape:

python main.py user test@example.com update password synthetic-example

In the original version, user was a leaf command and update was its sibling; a leaf command cannot then consume another sibling command. The callback and context patterns provide the group-level argument and per-invocation shared state.

I checked the full command path and rejection of a missing email with CliRunner on Typer 0.9.0 / Click 8.1.8 and Typer 0.27.3. This only tests argument routing, not a password-update implementation. For an actual password command, prefer a hidden prompt over putting a secret in shell history.
