Hi,
is there a way to delete custom fields (specifying the name) a custom field on all entries?
I have multiple due to import from keepass which are useless now.
Thanks.
Perhaps Bitwarden Password manager CLI? Or the associated vault management API using the serve command?
May also be possible to take a .json backup, edit the properties to remove the custom fields matching the name you are looking for and import the new edited files to a blank vault or simply into a separate folder and remove the original (now duplicate entries)
Thx. Did not realize there is a cli. Will check if this is scriptable.
Using the API this is some effort on coding (and not breaking) anything.
Remind myself capturing a backup before. 
If you also like I prefer to sign up for a simple free account (login credentials can ofc be stored in your Bitwarden vault as it’s simply a blank account, or however you feel best) and use that to test and experiment with.
Backups are good, and Bitwarden has recently introduced the ability to backup and Export out with attachments as well, but having a blank test account which can be blown up safely during debugging your code would be my suggestion.
You can easily apply the same backup from your main account and import to the test account, though then I would recommend to secure the “test” account a bit further since it has live data, or simply seed the account with a few examples items and logins to test.
Happy scripting

Thx for that feedback.
I am running in LXC and there is a daily backup for three weeks and I do snapshots every hours and keep them for three days.
So I am pretty covered (hopefully).
Let’s see how much these extra fields bother me to go for action.
