🦦 Otti

The one-time password (OTP for short) manager for the terminal, with interactive and fancy TUI.

What's an OTP?

An OTP is the abbreviation for One-Time Password and is usually part of a two-factor authentication setup. That is, when a second password is required for a login to some service as extra security measure.

It usually involves scanning a QR-Code from the service's website or inputting it into an authenticator manually.

Yet another OTP account manager?

I wanted an OTP manager app for the terminal that behaves similar as mobile managers but couldn't find any that work in that way. Most CLI-based existing managers use single commands to manage the OTP accounts, which are non-interactive.

Therefore, this is a different approach by using the awesome tui-rs crate to build a TUI variant that is as similar to the mobile apps as possible but still simplistic.

Additionally, I felt the way some OTP managers save the account information is to simple and weak in regards to security. Otti uses the orion crate for the credential storage which is very similar to libsodium, but fully implemented in Rust.

Installation

Pre-built binaries

Grab the binary for your OS from the releases, extract it and put it in a folder that's on your $PATH like /usr/local/bin.

From source

Make sure to have the latest Rust compiler and Cargo installed and run:

cargo install --git https://github.com/dnaka91/otti.git --tag v0.1.0

You can omit the --tag flag to install the latest development version, but make backups of your store file just in case.

From AUR

Arch Linux users can install Otti from the AUR using an AUR helper. For example:

paru -S otti

Usage

Currently Otti is read-only, that means you can not add any new accounts to its database. Instead you have to import from an external OTP manager until editing features are implemented.

To do so, first export your OTP accounts from one of the supported external apps (currently Aegis and andOTP), then run otti import <provider> <file> and optionally give a password with the --password argument if the import file is protected.

After the import completed successfully simply run otti, enter your password and use the TUI. For further help inside the TUI hit the h hotkey.
