Consider a scenario where security setting is too restrictive in your org. If there is a need to share some specific record with only couple of users or group and that too for one time sharing, instead of changing OWD setting or profile level setting or creating a permission set you can share those records manually directly from records detail page.
How to Enable Sharing button in detail page.
Step 1: Go to setup, in quick search type “Sharing Settings”, Click on Sharing Settings.
Step 2: In Organization-wide Default section, click “Edit”
Step 3: Select the Manual User Record Sharing checkbox to display the Sharing button on user detail pages, which enables users to share their records with others. Or deselect the checkbox to hide the button, which prevents users from sharing their user records with others.
Step 4: Click “Save”.


Once the permission is given user can see the Sharing button in detail page of a record.
Note: Sharing button is available in Salesforce Classic version only.
You can create a custom workaround to share record Manually in lightning. Or there are some app exchange applications which can help you.
How to grant access to a record with Manual sharing.

For all objects, except Account. You must select access level for the record.
- Read Only.
- Read/Write.
Account is an important object and Opportunities and cases can be accessed through account, So when a account record is shared, user should also mention the access that shared user will have on related opportunity and case records of that account, User can select one of the below option for opportunity access and case access.
- Private
- Read Only
- Read/Write.
Note:
- If you’re sharing an opportunity or case, the users you share it with must have at least Read access to the account (unless you are sharing a case via a case team). If you also have privileges to share the account itself, the users you share it with are automatically given Read access to the account. If you do not have privileges to share the account, you must ask the account owner to give others Read access to it.
- Contact Access is not available when the organization-wide default for contacts is set to Controlled by Parent.
- For sharing rules that specify access for associated object records, the given access level applies to that sharing rule only. For example, if an account sharing rule specifies Private as the access level for associated contacts, a user can access to associated contacts via other means. These means include org-wide defaults, the Modify All Data or View All Data permission, or the Modify All or View All permission for contacts.
There is an idea for the same
If you see sharing details screenshot, you can observe that there is one more button named Expand List, if you click that system will show list users who have access on the record.

You can observe the reason section in the7 list, which will inform how the record is shared with other users.
