How to Recover Email Passwords in Postbox (Step-by-Step Guide)

In this guide, you will learn where Postbox stores your saved email passwords, how they are secured using strong encryption, and the easiest way to recover them instantly when needed.
Postbox Password Secrets
Postbox stores all your email account credentials in a file named “logins.json”, located at:
C:\Users\[user_name]\AppData\Roaming\PostboxApp\Profiles\[random_name]\logins.json
This “logins.json” file is stored in JSON format and contains a separate entry for each saved account credential.
Below are the key fields included for every credential entry,
{
"id":1,
"hostname":"imap://mail.example.com",
"encryptedUsername":"MDIEEPgBBBBABBBEwFAYIbaZIhvcNAwcEaAFsqdqBAiJyHK56O9cid==",
"encryptedPassword":"MDoEEPgBCCCCAAAAAAEwFCDIKoZIBAtABCG4rNAexni08zRm4Sraz/",
},
To safeguard the secrets, Postbox uses the key that is derived from the Master Password. This key is then used to encrypt the username/password using SHA-1 and Triple DES encryption.
Postbox Master Password
Postbox allows you to set a Master Password to protect all your stored email passwords. Once enabled, the stored passwords cannot be decrypted without providing this Master Password.
The Master Password itself is secured using a one-way hashing algorithm, meaning it cannot be directly decrypted. The only possible recovery method is through a brute-force attack, which can take a very long time depending on the password’s length and complexity.
Postbox stores Master Password–related data in the files key4.db and cert9.db, located in the same profile folder. Older versions used key3.db and cert8.db.
Important Tip: Since Postbox does not use user-specific or machine-bound encryption, its passwords from other user account or external drive can be recovered using the software mentioned below.
