Got it — on SQL Managed Instance you should do the classic SQL login (instance-level) + database user (per DB) + roles/GRANTs. That gives you username/password now, and later you can swap the user mapping to Entra without redesigning your permissions model. ([Microsoft Learn]1)

1) Create one SQL Login per person (don’t share)

Run in master:

USE [master];
GO

CREATE LOGIN [dev_john] WITH
  PASSWORD = 'Use-A-Long-Random-Password-Here!',
  CHECK_POLICY = ON,
  CHECK_EXPIRATION = ON,
  DEFAULT_DATABASE = [HomeaZZonDb1];
GO

(Repeat for each guy.) Managing logins/users is standard for Managed Instance. ([Microsoft Learn]1)

---

2) Create a user only in the 1–2 databases they’re allowed to access

Database #1:

USE [HomeaZZonDb1];
GO

CREATE USER [dev_john] FOR LOGIN [dev_john];
GO

-- Simple broad read-only:
ALTER ROLE db_datareader ADD MEMBER [dev_john];
GO

Database #2 (optional):

USE [HomeaZZonDb2];
GO

CREATE USER [dev_john] FOR LOGIN [dev_john];
GO

ALTER ROLE db_datareader ADD MEMBER [dev_john];
GO

Database roles (like db_datareader) are the clean way to manage permissions. ([Microsoft Learn]2)

---

3) If “read-only to the whole DB” is too broad, do least-privilege (recommended)

Instead of db_datareader, create a custom role and grant only what you want:

USE [HomeaZZonDb1];
GO

CREATE ROLE [AppReadOnly];
GO

-- Option A: all tables in dbo schema
GRANT SELECT ON SCHEMA::dbo TO [AppReadOnly];
GO

-- Option B: only specific tables
-- GRANT SELECT ON dbo.Table1 TO [AppReadOnly];
-- GRANT SELECT ON dbo.Table2 TO [AppReadOnly];

ALTER ROLE [AppReadOnly] ADD MEMBER [dev_john];
GO

(If they need stored procs only, grant EXECUTE instead of SELECT.)

---

4) How this prevents access to other databases

If you don’t create a user for that login in other databases, they can’t access them (they’ll get “not authorized” when trying to USE OtherDb). To avoid any accidental access via guest in user databases, you can revoke guest connect in databases you don’t want anyone drifting into: ([Microsoft Learn]3)

-- Run inside EACH user database you want locked down (NOT master/tempdb; be careful with msdb)
REVOKE CONNECT FROM GUEST;
GO

Note: Disabling guest in msdb can break features (SQL Agent-related behavior), so don’t do it there. ([Microsoft Learn]4)

---

5) Operational tips (worth doing)

• Disable the login when you’re done (instant cutoff):

  ALTER LOGIN [dev_john] DISABLE;

• Keep them out of server roles (don’t add to anything like sysadmin).

• Use separate logins per person so auditing is real.

If you tell me what “access” means (read-only vs read/write vs execute-only, and whether they need migrations/scaffolding), I’ll tailor the exact role + GRANT script for those 1–2 databases.

Yes. What you’re seeing is normal: by default, SQL Server grants database name visibility broadly via the server permission VIEW ANY DATABASE (it’s granted to the public server role by default), so logins can see all DBs even if they can’t use them. ([Database Administrators Stack Exchange]1)

Best fix (per-login): deny “view any database”

Run in master:

USE [master];
GO
DENY VIEW ANY DATABASE TO [dev_john];
GO

After this, in SSMS Object Explorer they should only see databases they can actually connect to (i.e., the 1–2 DBs where you created a user/mapped permissions), plus some system DB behavior depending on SSMS. ([Stack Overflow]2)

Cleaner at scale: create a server role and deny once

USE [master];
GO

CREATE SERVER ROLE [LimitedDbVisibility];
DENY VIEW ANY DATABASE TO [LimitedDbVisibility];

ALTER SERVER ROLE [LimitedDbVisibility] ADD MEMBER [dev_john];
ALTER SERVER ROLE [LimitedDbVisibility] ADD MEMBER [dev_mike];
GO

This is easier than managing DENY statements on each login.

Important notes

• If they’re sysadmin (or in powerful server roles), you won’t be able to hide anything — they’ll see all DBs. ([Server Fault]3)
• You generally can’t fully hide system databases at the engine level; SSMS may still show them. That’s by design. ([Microsoft Learn]4)
  (SSMS has a client-side option “Hide system objects,” but that’s per workstation, not security.) ([Database Administrators Stack Exchange]5)

Undo (if needed)

USE [master];
GO
REVOKE VIEW ANY DATABASE TO [dev_john];
GO

If you want, paste one login name and your allowed DB names and I’ll give you a single script that: creates login, maps user in only those DBs, grants read/write, and applies the “don’t show other DBs” setting.
