Expected response code 250 but got code “535”, with message \"535-5.7.8 Username and Password not accepted

Question

I recently encountered a SwiftMail error while trying to send a mail through gmail.

 Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted.

I was trying to send mail through my gmail and google thought that I was a spam(maybe because I was requesting too fast) I received a mail from them saying my account was access and I told them it was me. I was able to send mail without problem and it just occured now.

This is the contents of my env file.

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=talentscoutphil@gmail.com
MAIL_PASSWORD=mypasswordhere
MAIL_FROM=talentscoutphil@gmail.com
MAIL_NAME=talentscout

Answer 1

I researched on the internet and some answers includes enabling the "access for lesser app" and "unlocking gmail captcha" which sadly didn't work for me until I found the 2-step verification.

What I did the following was:

1. enable the 2-step verification to google HERE

2. Create App Password to be use by your system HERE

3. I selected Others (custom name) and clicked generate

4. Went to my env file in laravel and edited this

   MAIL_USERNAME=talentscoutphil@gmail.com

   MAIL_PASSWORD=thepasswordgenerated

5. Restarted my apache server and boom! It works again.

This was my solution. I created this to atleast make other people not go wasting their time researching for a possible answer.

Answer 2

I had the same problem, changing my gmail password fixed the issue, and also don't forget to enable less secure app on on your gmail account

Answer 3

I had everything fine. Less secure app option was also enabled. Still, I was getting the error. What I have done is:

• Google will send you Critical security alert
• Then you have to authorize that activity. ( Clicking on 'YES, THAT WAS ME' type thing )
• Then you can try sending email again.

Answer 4

i had same issue i resolve this use under

go to gmail.com

my account

and enable

Allow less secure apps: ON

it start works

Answer 5

This single step worked for me... No 2-step verification. As I had created a dummy account for my local development, so I was OK with this setting. Make sure you only do this if your account contains NO personal or any critical data. This is just another way of tackling this error and NOT secure.

I turned ON the setting to alow less secured apps to be allowed access. Form here : https://myaccount.google.com/lesssecureapps

Hope this helps your purpose.

Answer 6

Gmail tends to block usage of mailing addresses which are being used in other applications as username for security reasons. Either you should create a new email address for mail purpose or you must go to the Less Secure App Access and turn on the access for less secure apps. Gmail will send you a mail for confirmation from where you can verify that those changes were made by yourself. Only then, you can use such mailing addresses for mailing purpose through applications.

Answer 7

This is my .env mail settings

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=587
MAIL_USERNAME=example@gmail.com
MAIL_PASSWORD=hello27
MAIL_ENCRYPTION=tls

i was getting thesame error as stated in the question but by using

php artisan config:cache

Everything worked fine
