When using Cognito's forgotPassword function, I get a 'LimitExceededException' error if I try to run the forgot password method more than 5 times.
Is there further documentation on this at this point?
This question brought up a similar point several years ago, but there was not guidance on any documentation. And this question brought up a similar issue, with comments noting in frustration there is no guidance on how long to wait.
I am hoping there is guidance available on:
How long does a user need to wait before trying it again? It's not helpful to my users to say "Please try again later", without any guidance on when. In my testing, I waited more than 30 minutes after, and the error still appears. This seems excessive for users.
Can I add this protection to the signin process? (not just the reset password process). This security protection does not appear to occur in the case of signing in. There, I can enter an incorrect password multiple times without a "too many attempts" type warning. I'd assume that is an important security step.
According to https://docs.aws.amazon.com/cognito/latest/developerguide/amazon-cognito-user-pools-authentication-flow.html,
We allow five failed sign-in attempts. After that we start temporary lockouts with exponentially increasing times starting at 1 second and doubling after each failed attempt up to about 15 minutes. Attempts during a temporary lockout period are ignored. After the temporary lockout period, if the next attempt fails, a new temporary lockout starts with twice the duration as the last. Waiting about 15 minutes without any attempts will also reset the temporary lockout. Please note that this behavior is subject to change.

I need to implement a lock and unlock mechanism in opendj 2.6 based on a fixed failed login attempt. I've already seen that there are two methods (https://backstage.forgerock.com/docs/opendj/2.6/admin-guide/#chap-account-lockout). a manual method (which I don't care about at all because I've already done some testing and found that it only allows manual locking and unlocking) and the second one which was perfect for me because, by modifying the password policy, it allows me to set a fixed number of failed attempts and set a lockout time out.
my goal: I need to find a way to unlock this type of locked users without spending the entire lockout time.
my problem: i have already read the documentation and apparently resetting the user's password is the only way.
ps: I also noticed that, when a user is locked, some attributes are added to his entry, such as: pwdAccountLockedTime and I thought I could delete this attribute manually, but that field was a non-editable field (and also I had no certainty that it would work).
Do you have any suggestions? Or is it simply not allowed?
As you have already identified, the proper way to unlock an account after N consecutive failures is to reset the password. If a user is entering a wrong password 5 times, do you think he will know the correct one the 6th time ?
Otherwise, OpenDJ has a tool called manage-account, where specific operations are possible. This should only be used by an admin with care.
I believe not all operations are documented, but you may read the code to understand them all.
I am using a python connector to use snowflake from backend , I need a query or something to check whether my account is valid or it got expired basically for trial account, In Snowflake UI it is showing the error but when using the python connector I need to get a similar error like at the time of login itself
"you trail has expired" is not really a thing that people "normally" need to programmatically know about.
Unless you are repeatedly "programmatically" making more accounts, which seems against the purpose of the free accounts.
I would think that you python would start failing to log in, which it should back off and try again after an escalating timer (1s, 10s, 60s,..) but at the same time tell you there is a failure (of some sort) and at the time the account expires. You stop running your automation/python code.
Hi there stack exchange,
We're seeing numerous issues in our environment of misconfigured systems repeatedly trying old passwords and causing the accounts to be locked out.
I can see no value in locking out accounts where the same password is tried multiple times, this does not get a (potential) attacker any closer to guessing the password as far as I can work out? I would like to know if there is a way to securely configure a system to count the number of distinct/unique password attempts per user, rather than just the number of attempts before lockout occurs?
I can appriciate that recording password attempts using a reversable derivitive might be bad for security, but surely there's a way to distinguish if the same password is attempted multiple times? Recording recent attempts in a long hash or something?
At the very least is it possible for a system to know that the immediately previous password has been attempted, or even a few back, and not count those as failed attempts? I have seen this implemented and it would seem simmilar to the need to judge uniqueness/distinction?
If the only purpose of a lockout policy is to prevent online brute force password guessing, rather than as a tool to DoS accounts, why is incrementing failed logon counters after only distinct password attempts uncommon?
Lots of question marks sorry, but for clarity the main question is again;
I would like to know if there is a way to securely configure a system to count the number of distinct/unique password attempts per user, rather than just the number of attempts before lockout occurs?
Thanks for any thoughts!
Kind regards,

When I tried to add some accounts to yodlee, the program took a long time to refresh the accounts. After refreshing for more than 3 mins, the program threw the exception "InvalidConversationCredentialsExceptionFaultMessage" or "StaleConversationCredentialsExceptionFaultMessage".
I have several accounts with this problem. All the other accounts work fine.
Could somebody tell me why these kinds of exceptions happen and how to solve them?
Thanks a lot.

You get "InvalidConversationCredentialsExceptionFaultMessage" when the user context gets expired. This can be corrected by re initiating the user context
With respect to "StaleConversationCredentialsExceptionFaultMessage", you get this when yout ry logging in the same user multiple times (create user contexts)and try to use the user context that is already invalid by the subsequent one.
Please let me know if you need more information.

I'm wondering when login timeouts are being used, specifically when using same session (same browser session). On a number of sites I have completed recently I have added 60 minute timeouts and they seem to be causing problems, such as users are not able to fill out larger forms (like a resume submission--people don't think of copying their resume from another program or saving part way through). On one site, I have implemented a div/popup forcing the user to enter their password to continue in the current session, without having to login again.
But on other sites, such as Facebook, it seems you are never logged out as long as you are using the same browser window, even without "remembering" your password.
The main reason I usually use timeouts is to ensure the data is secure, such that another party can't sit down at the computer a few hours later and use the system as the original user.
I'm wondering how you decide when a site should time out users because of inactivity?
I'm thinking the answer would be language agnostic.
IMO, they're valid when:
security is critical (ie. banking)
the likelihood of seat-swapping is
high (ie. public terminals)
Regardless, there may be instances like your resume system, where you want people on public terminals to be able to carry out an act that may leave them inactive for longer than your desired or necessary timeout.
I suppose you just have to handle that in a smart fashion - either figure out a way they can get the data in quicker (which would be ace, spending an hour filling out a form is not fun - can they just upload a file?), or ensuring they can continue without any data loss after being prompted to log in again.
Even though 60 minutes seems like a long time to fill out a single form (perhaps the forms should be divided into multiple pages?), you can probably use SlidingExpiration to solve the problem where your users get logged out even though the browser session is alive.
I think the timeout for an auth cookie is a Security level decision. If your site is SSL secured, you would probably have minimal timeout values (user session would expire within a matter of minutes). On the other hand, for sites with non-critical security, you could set a medium timeout value.
When I sign on to online banking, for example, it asks me whether or not I am using a "public terminal": and if I say yes then it enforces stricter security, or if no then laxer.
