Account

Signing in and out, account settings, and the sessions Proton holds for you.

Every command and flag is in the proton account reference. For profiles, environment variables and where things are stored, see Configuration.

Where you stand

$ proton account get
Email:       you@proton.me
Name:        Roman
Storage:     128.4 GB of 500 GB (26%)
Max Upload:  5.0 GB
Profile:     default
Session:     valid
Unlocked:    yes
ID:          Kd91mQxT…

Session: valid and Unlocked: yes together mean this machine can act as the account right now.

Signing in and out

proton account login
proton account logout
proton account logout --revoke     # also invalidate it at Proton
proton account logout --all        # every profile on this machine

login asks for whatever a flag has not already supplied, as long as it is running in a terminal. Without one, name the account with --user and hand the password over with --password-file or --password-stdin (why not --password).

It also unlocks your keys, so your password is needed once per machine and not again. Signing in again as the same account changes nothing, so an unattended job can run it ahead of its real work and recover on its own from a session that expired.

Security keys are not supported: they need a browser. If your account uses one, add an authenticator app in Proton’s settings and sign in with that code.

Profiles

A profile is a named session slot on this machine, so a personal and a work account never mix.

$ proton --profile work account login
✓ Signed in as you@company.com (profile "work").

$ proton account profiles list
PROFILE   EMAIL             UNLOCKED  SAVED             ACTIVE
────────  ────────────────  ────────  ────────────────  ──────
default   you@proton.me     yes       2026-04-15 14:31  ✓
work      you@company.com   yes       2026-04-15 15:02

profiles list works offline. export PROTON_PROFILE=work makes one the default for a shell.

Sessions

Every session Proton holds for your account, across all your devices - the “Sessions” section of Proton’s account settings.

$ proton account sessions list
ID        CLIENT     CREATED           CURRENT
────────  ─────────  ────────────────  ───────
7Kd91mQx  web-mail   2026-04-15 14:31  ✓
3Ns8pT2v  ios-mail   2026-03-02 08:11
9xL4pQrT  web-drive  2026-01-20 19:44

proton account sessions revoke 3Ns8pT2v
proton account sessions revoke --others     # everything but this one

If you lose a device, revoke its session. That also makes the credentials saved on it useless, even to someone who already copied the file.

Settings

proton account settings get     # the values now in effect
proton account settings list    # the keys you can change, with their values
proton account settings set locale de_AT

Key	Values
`locale`	any text, e.g. `de_AT`
`date-format`	`locale`, `dd/mm/yyyy`, `mm/dd/yyyy`, `yyyy-mm-dd`
`time-format`	`locale`, `24h`, `12h`
`week-start`	`locale`, `monday` … `sunday`
`crash-reports` · `telemetry`	`off`, `on`

Values can be given by name or by Proton’s own number, and mistakes are caught before anything is sent.

get shows more than set can change. Proton Sentinel, two-factor state and recovery addresses are readable here but can only be changed at account.proton.me, along with your password, recovery secrets, billing and account deletion.

Mail, Calendar and Drive each have settings of their own - proton mail settings, and so on. Pass and Contacts have none.
