Yes. You can assign LastPass provisioning to specific groups in the OneLogin dashboard, and groups themselves are synced from OneLogin to LastPass.

Yes, you can assign as many custom groups to LastPass in the OneLogin dashboard as needed.

If you add or remove users to a group in OneLogin, the change will be reflected in LastPass and an account will be provisioned or deprovisioned as needed.

No. Users must create a separate LastPass master password when they receive their account invitation. The master password is used to form the encryption key to their LastPass vault, and is never shared with LastPass (or OneLogin).

No, users are automatically provisioned and will appear as live users.

When first deploying LastPass Business with OneLogin, you can set up a small test group in OneLogin. Once you’ve confirmed that provisioning is working as expected, you can test adding and removing people in the test group. Once all testing is successful, you can then assign LastPass to all groups, or the specific groups that will be using LastPass.

Users who are created via automated provisioning using directory integrations (i.e., SCIM provisioning or federated login) are automatically sent an activation code via email, which is required for finishing the account setup process. For this reason, the Don't send welcome email policy does not affect users created via automated provisioning.
