# Choose an access method

Note: This choice depends on the company policy and how the Google Cloud project has been set up. Refer to the Google documentation to check all the VM access options.

The following are considerations to be kept in mind when deciding on the access method:

- If there are other Linux virtual machine instances running on Google Cloud, you might need to share or restrict their user or application access to your VMs

- If user access to your Linux VM instances must be managed, you can use one of the following methods:

  - OS Login

  - Metadata SSH keys management

  - Temporarily user access granted to an instance

For this deployment example, the chosen method is SSH keys.
