topt

A simple program that reads TOTP URIs from standard input and generates OTP codes, outputs the codes in various formats (plain text, JSON, or table).

Installation

go install github.com/towsifkafi/topt@latest

If you want to build it yourself, feel free to clone the repository and run go build

Usage

# passing the URI as an argument
topt "otpauth://totp/Example%20OTP?secret=verysecret&algorithm=SHA1&digits=6&period=30"

# pipe into topt
echo "otpauth://totp/Example%20OTP?secret=verysecret&algorithm=SHA1&digits=6&period=30" | topt

# Output: Name: Example OTP, OTP Code: 524777

# it also supports multiple URIs at once (should be separated by newlines)

# if you have it in clipboard
