`dvc exp` commands always request my passphrase.

Bug Report

dvc exp commands always request my passphrase.

Description

Hello, I have the following unwanted behavior. First of all my config looks like this:

[core]
    remote = nas_remote
[cache]
    dir=/fastdata/data/dvc_cache
    type = symlink
[hydra]
    enabled = True
['remote "nas_remote"']
    url = ssh://192.168.93.111:/data/slidespeicher/projects/data/annotations/dvc_setup
    verify = true
    keyfile = /home/deep/.ssh/priv_key.openssh
    user = lefos
    port = 22
    ask_password = false
    ask_passphrase = true

Especially the lines

    ask_password = false
    ask_passphrase = true

are necessary because I connect to my NAS (the remote DVC cache) by using a private key, which works fine by the way. :heavy_check_mark:

I was working with dvc repro and I am changing to dvc exp run and I noticed that whenever I run any dvc exp command (e.g. dvc exp show or dvc exp run), I get the following prompt: Enter a passphrase for host '192.168.93.111' port '22' user 'lefos':. This is normal to be requested when I interact directly with my remote with commands like dvc pull or dvc push, but especially for commands like dvc exp run, it is annoying because it is being requested for each dvc stage.

Hi @lefos99 , thanks for the report. I am looking into it.

As a current workaround, have you tried setting the following:

dvc remote modify --local nas_remote passphrase mypassphrase

[daavoo]

Do you have any dvc imported data in your pipeline?

Thanks @daavoo :smiley_cat:

No, not at all.

As a current workaround, have you tried setting the following:

dvc remote modify --local nas_remote passphrase mypassphrase

This works, but I don't like that my private password is stored in a file (.dvc/config or .dvc/config.local) 😕

@daavoo Were you able to look into this?
