If you are working with enrollments in user accounts, do note that the enrollment token handling is now separate from reset password token. The token is now under services.password.enroll, so adjust your code accordingly if you use it.
Lots of internal calls to Meteor.user() without field specifiers in accounts-base andaccounts-password packages have been optimized with explicit field selectors to onlythe fields needed by the functions they are in.Issue #10469

The accounts-ui-unstyled package has been updated to use and tags with its login/signup form, instead of 's. Thischange helps browser's notice login/signup requests, allowing them totrigger their "remember your login/password" functionality.
accounts-password now uses example.com as a default "from" address insteadof meteor.com. This change could break account-related e-mail notifications(forgot password, activation, etc.) for applications which do not properlyconfigure a "from" domain since e-mail providers will often reject mail sentfrom example.com. Ensure that Accounts.emailTemplates.from is set to aproper domain in all applications.PR #8760
The accounts-password Accounts.emailTemplates can now specify arbitraryemail headers. The from address can now be set separately on theindividual templates, and is a function there rather than a staticstring. #2858 #2854
Switch accounts-password to use bcrypt to store passwords on theserver. (Previous versions of Meteor used a protocol called SRP.)Users will be transparently transitioned when they log in. Thistransition is one-way, so you cannot downgrade a production app onceyou upgrade to 0.8.2. If you are maintaining an authenticating DDPclient:
Now, for sending the actual emails. There are a couple of ways to go about this. First, and the one that I have used in this post is, by using a gmail address. I will advise you not to use your permanent Gmail address for this. Make one or two new ones that you can use specially for sending bulk mails. This is just a safety measure. Google may think that you were spamming other people and may suspend your account. So, we are using a separate account for this purpose.
Contrary to what the name suggests, rainbow tables are nowhere as picturesque and pose a severe threat to users and businesses using the digital world. This article will attempt to break down the hows and whats of a rainbow table and arm you with knowledge on preventing a rainbow table attack. Primarily used as the base of a password cracking tool, this table helps crack password hash values or crack passwords.
A rainbow table attack is a type of hacking in which an attacker tries to use a rainbow hash table to crack the hash value of passwords stored in a database. It is a collection of precomputed dictionaries of plaintext passwords and their corresponding hash values that can be useful in finding what plaintext password produces a particular hash.
Password hashing is a method by which plain text passwords are encrypted using some hashing algorithm. Hashing passwords makes it impossible for an attacker to reverse the password hash to the plaintext password, and even a tiny change in the input would drastically change the output value. Whenever you hear or read about hashed passwords being stolen, attackers have the challenge to crack these passwords using a password cracking method before they see clear-text passwords.
Rainbow tables are often thought of as simple large databases of scomplex or straightforwardpasswords or hash combinations. Even though this is how the mechanism of rainbow tables appears to work from the outside, this is not how rainbow tables work internally. The precomputation process of the hashes has obvious advantages in storage. Storing a large amount of data plainly in a database would require much more memory than when it is stored in the form of hashes in a rainbow table. Hence, not only does the rainbow table makes cracking password hash value faster, but it also saves expenses in storage.
In other traditional password cracking methods, when an attacker gets access to a hashed password file from a database, the attacker must first analyse the hashes and find out which type of hashing algorithm is used.
After this process, the attacker then applies the same algorithm to the password dictionary file containing plaintext passwords or generates a custom password file for performing a brute force attack on the password. This makes the whole process of password cracking rather time-consuming.
These issues can be avoided by using a rainbow table, rainbow tables help to compare a password hash with the values in the rainbow table and returns the one with the same hash value. Rainbow tables make the password cracking process much easier and less time-consuming.
The main difference between a brute force attack and a rainbow table attack is that there is precomputed data involved with a rainbow table when trying to crack passwords whereas there is no precomputed data when a brute force is to be performed. Rainbow tables greatly speed up the process compared to brute force attacks. Some software can crack password hashes of 14-characters in under 160 seconds!
If a system uses outdated applications with vulnerabilities, this can lead to an attacker taking advantage of this weakness and planting a backdoor/malware in the system. The attacker then escalates his privileges and dumps the password hashes. Using a rainbow table, they can then decrypt the passwords of all user accounts in the system.
Key stretching: Another method is key stretching, in which, the possible salt value, password and some random hash values are passed through the hash function multiple times to increase the computation time required to hash each password which can make a stolen passwords file less useful to a hacker as he would require more computing power.
If OpenAM stores attributes in Active Directory, for example to manage account lockout, or if Active Directory requires that OpenAM authenticate in order to read users' attributes, then OpenAM needs the DN and password to authenticate to Active Directory.
If OpenAM stores attributes in the LDAP directory, for example to manage account lockout, or if the LDAP directory requires that OpenAM authenticate in order to read users' attributes, then OpenAM needs the DN and password to authenticate to the LDAP directory.
Specifies one or more Java classes used to provide a callback mechanism for user status changes during the authentication process. The Java class must implement the com.sun.identity.authentication.spi.AMAuthCallBack OpenAM interface. OpenAM supports account lockout and password changes. OpenAM supports password changes through the LDAP authentication module, and so the feature is only available for the LDAP module.
If OpenAM stores attributes in the directory, for example to manage account lockout, or if the directory requires that OpenAM authenticate in order to read users' attributes, then OpenAM needs the DN and password to authenticate to the directory.
The Open Authentication (OATH) module provides a more secure method for users to access their accounts with the help of a device, such as their mobile phone or Yubikey. Users can log into OpenAM and update their information more securely from a one-time password (OTP) displayed on their device. The OATH module includes the OATH standard protocols (RFC 4226 and RFC 6238). The OATH module has several enhancements to the HMAC One-Time Password (HOTP) Authentication Module, but does not replace the original module for those already using HOTP prior to the 10.1.0 release. The OATH module includes HOTP authentication and Time-Based One-Time Password (TOTP) authentication. Both types of authentication require an OATH compliant device that can provide the OTP.
HOTP authentication generates the OTP every time the user requests a new OTP on their device. The device tracks the number of times the user requests a new OTP, called the counter. The OTP displays for a period of time you designate in the setup, so the user may be further in the counter on their device than on their account. OpenAM will resynchronize the counter when the user finally logs in. To accommodate this, you set the number of passwords a user can generate before their device cannot be resynchronized. For example, if you set the number of HOTP Window Size to 50 and someone presses the button 30 on the user's device to generate a new OTP, the counter in OpenAM will review the OTPs until it reaches the OTP entered by the user. If someone presses the button 51 times, you will need to reset the counter to match the number on the device's counter before the user can login to OpenAM. HOTP authentication does not check earlier passwords, so if the user attempts to reset the counter on their device, they will not be able to login until you reset the counter in OpenAM to match their device.
TOTP authentication constantly generates a new OTP based on a time interval you specify. The device tracks the last two passwords generated and the current password. The Last Login Time monitors the time when a user logs in to make sure that user is not logged in several times within the present time period. Once a user logs into OpenAM, they must wait for the time it takes TOTP to generate the next two passwords and display them. This prevents others from being able to access the users account using the OTP they entered. The user's account can be accessed again after the generation of the third new OTP is generated and displayed on their device. For this reason, the TOTP Time-Step Interval should not be so long as to lock users out, with a recommended time of 30 seconds.
Two step verification is an authentication technique that requires users to provide multiple forms of identification when logging in to OpenAM. Two step verification provides a more secure method for users to access their accounts with the help of a device supported by the ForgeRock Authenticator (OATH) authentication module. Users can log in to OpenAM more securely by using a generated one-time password. 2ff7e9595c
