1Password review
If an editor needs a login for one afternoon, I want to hand over that one entry and keep the rest of my vault private. 1Password lets me send a copy of a saved item in a link. The editor can open it in a browser without a 1Password account.
Give the link a deadline
When creating a link, I can choose when it expires and limit it to specific email addresses. In that case, the recipient has to verify their address before opening the item. I’d check that the entry contains only the login details I mean to share. The link opens a copy of the entry as it was when I sent it. If I correct the username later, I need a new link.
Decide what ends when the link closes
I can remove a link from the item’s sharing history before it expires. Someone who already opened it can still have a copy of the password. That matters for a one-off handover. Where the site offers a separate account for the editor, I’d use one so I can close that account after the job.
For two people who maintain the same site every week, I’d look at a shared collection such as the one in Bitwarden. Its organization owns the items in that collection, and access follows collection membership. A temporary 1Password link makes more sense for handing over one copy for a specific job.
Anabel’s take
I’d use an email-restricted link for a one-off job on a staging site. I’d keep the main admin login to myself and make sure I have a way to end the editor’s access to the staging site after delivery. That’s a separate decision from how long the link stays open.
