Open with RSA SecurID Software Token. Available for Windows and Mac.

What is a .SDTID file?

An .SDTID file is a type of file known as a SecurID Soft Token File. It is used by a program called RSA SecurID Software Token, which helps verify who someone is and controls their access to different computer networks. This file contains important information like the name of the token profile, the type of device it's for, how long the token code lasts, how many digits are in the token code, the type of authentication used, how the token is delivered, and details specific to the device.

These .SDTID files are usually protected by a strong type of security known as 128-bit AES encryption, and they are often sent in .ZIP files to keep them secure. The main programs that can open these files are RSA SecurID Software Token and RSA SecurID Software Token Converter, available on different platforms including Windows, iOS, and Android.

More about these files: Tokens are like digital keys that let a user access a computer system or a secure area. A soft token, which is a kind of virtual key, is created and given to approved users to confirm that their device is safe to use within a secure network or to connect to a server. The .SDTID file is how RSA sends these digital keys to users so they can get into the network they need.

Usually, these files are shared through email or downloaded from a website that requires users to log in first. To use the .SDTID file, you need to have the RSA SecurID Software Token program installed. This program checks your identity and lets you into the network. If you need to use the token on mobile devices like phones or tablets, you can convert the .SDTID file into a format called a Compressed Token Format (CTF) string using the RSA Software Token Converter. This makes it compatible with devices running Android or iOS.
