 ### Import/Export
 You can import backups made by [Aegis](https://github.com/beemdevelopment/Aegis) and [andOTP](https://github.com/andOTP/andOTP) Authenticators, but backup compatibility is growing (check [planned features](#planned-features)).
 By typing `cotp -ex` you can export your database in unencrypted json format.
+### Compatibility
+cotp can generate two-factor authentication coded using HMAC-SHA1, HMAC-SHA256 and HMAC-SHA512, with any digits, to provide a good compatibility to most two-factor authentication systems.
 ### Cross Plaform
 Thanks to the glorious [Rust Language](https://www.rust-lang.org/) cotp is easily **compilable** in every platform supported by rust itself.
 As now i personally tested program functionalities in these systems:

 Please note that cotp requires at least an 8 chars length password.
 If you type `cotp -h` you get some instruction on how to use cotp utilities.
